An Amber Alert (alternatively styled AMBER alert) or a child abduction emergency alert (SAME code: CAE) is a message distributed by a child abduction alert system to ask the public for help in finding abducted children. The system originated in the United States.

AMBER is a backronym standing for America's Missing: Broadcast Emergency Response. It was created in reference to Amber Rene Hagerman, a girl who was abducted and later found murdered in 1996. Alternative regional alert names were once used; in Georgia, "Levi's Call" (in memory of Levi Frady); in Hawaii, "Maile Amber Alert" (in memory of Maile Gilbert); in Arkansas, "Morgan Nick Amber Alert" (in memory of Morgan Nick); and in Utah, "Rachael Alert" (in memory of Rachael Runyan).

In the United States, Amber alerts are distributed via commercial and public radio stations, Internet radio, satellite radio, television stations, text messages, and cable TV by the Emergency Alert System and NOAA Weather Radio (where they are termed "Child Abduction Emergency" or "Amber Alerts"). The alerts are also issued via e-mail, electronic traffic-condition signs, commercial electronic billboards, or through wireless device SMS text messages.

AMBER Alert has also teamed up with Google,Bing, and Facebook to relay information regarding an AMBER Alert to an ever-growing demographic: AMBER Alerts are automatically displayed if citizens search or use map features on Google or Bing. With the Google Child Alert (also called Google AMBER Alert in some countries), citizens see an AMBER Alert if they search for related information in a particular location where a child has recently been abducted and an alert was issued. This is a component of the AMBER Alert system that is already active in the US (there are also developments in Europe). Those interested in subscribing to receive AMBER Alerts in their area via SMS messages can visit Wireless Amber Alerts, which are offered by law as free messages. In some states, the display scrollboards in front of lottery terminals are also used.

The decision to declare an AMBER Alert is made by each police organization (in many cases, the state police or highway patrol) that investigates each of the abductions. Public information in an AMBER Alert usually consists of the name and description of the abductee, a description of the suspected abductor, and a description and license plate number of the abductor's vehicle if available.

Activation criteria

The alerts are broadcast using the Emergency Alert System, which had previously been used primarily for weather bulletins, civil emergencies, or national emergencies. In Canada, alerts are broadcast via Alert Ready, a Canadian emergency warning system. Alerts usually contain a description of the child and of the likely abductor. To avoid both false alarms and having alerts ignored as a "wolf cry", the criteria for issuing an alert are rather strict. Each state's or province's AMBER alert plan sets its own criteria for activation, meaning that there are differences between alerting agencies as to which incidents are considered to justify the use of the system. However, the U.S. Department of Justice issues the following "guidance", which most states are said to "adhere closely to" (in the U.S.):

1. Law enforcement must confirm that an abduction has taken place.
2. The child must be at risk of serious injury or death.
3. There must be sufficient descriptive information of child, captor, or captor's vehicle to issue an alert.
4. The child must be under 17 years of age.

Many law enforcement agencies have not used #2 as a criterion, resulting in many parental abductions triggering an Amber Alert, where the child is not known or assumed to be at risk of serious injury or death. In 2013, West Virginia passed Skylar's Law to eliminate #1 as a criterion for triggering an Amber Alert.

It is recommended that AMBER Alert data immediately be entered into the Federal Bureau of Investigation (FBI) National Crime Information Center. Text information describing the circumstances surrounding the abduction of the child should be entered, and the case flagged as child abduction.

The Royal Canadian Mounted Police's (RCMP) requirements in Canada are nearly identical to the above list, with the exception that the RCMP is notified. One organization might notify the other if there is reason to suspect that the border may be crossed.

When investigators believe that a child is in danger of being taken across the border to either Canada or Mexico, U.S. Customs and Border Protection, United States Border Patrol and the Canada Border Services Agency are notified and are expected to search every car coming through a border checkpoint. If the child is suspected to be taken to Canada, a Canadian Amber Alert can also be issued, and a pursuit by Canadian authorities usually follows.

Incidents not meeting alert criteria

For incidents which do not meet AMBER Alert criteria, the United States Department of Justice developed the Child Abduction Response Teams (CART) program to assist local agencies. This program can be used in all missing children's cases with or without an AMBER alert. CART can also be used to help recover runaway children who are under the age of 18 and in danger. As of 2010, 225 response teams have been trained in 43 states, as well as Washington, D.C., Puerto Rico, the Bahamas, and Canada.

Parent(s)	Donna Williams, Richard Hagerman

Amber Rene Hagerman (November 25, 1986 – January 15, 1996) was a nine-year-old girl abducted while riding her bike in Arlington, Texas. Her younger brother, Ricky, had gone home without her because Amber had wanted to stay in the parking lot for a while. When he returned with his grandfather, they only found her bicycle. A neighbor who had witnessed the abduction called 911.

On hearing the news, Hagerman's father, Richard, called Marc Klaas, whose daughter, Polly, had been kidnapped and murdered in Petaluma, California, in 1993. Amber's mother, Donna Whitson (now Donna Williams), called the news media and the FBI. They and their neighbors began searching for Amber.

Four days after her abduction, near midnight, a man walking his dog discovered Amber's naked body in a creek behind an apartment complex with severe laceration wounds to her neck. The site of the discovery was less than five miles (8 km) from where she was abducted. Her murder remains unsolved as of 2023.

Texas program development

Within days of Amber's death, Donna Williams was "calling for tougher laws governing kidnappers and sex offenders". Amber's parents soon established People Against Sex Offenders (PASO). They collected signatures hoping to force the Texas Legislature into passing more stringent laws to protect children.

God's Place International Church donated the first office space for the organization, and as the search for Amber's killer continued, PASO received almost-daily coverage in local media. Companies donated various office supplies, including computer and Internet service. Congressman Martin Frost, with the help of Marc Klaas, drafted the Amber Hagerman Child Protection Act. Both of Hagerman's parents were present when President Bill Clinton signed the bill into law, creating the national sex offender registry. Williams and Richard Hagerman then began collecting signatures in Texas, which they planned to present to then-Governor George W. Bush as a sign that people wanted more stringent laws for sex offenders.

In July 1996, Bruce Seybert (whose own daughter was a close friend of Amber) and Richard Hagerman attended a media symposium in Arlington. Although Hagerman had remarks prepared, on the day of the event the organizers asked Seybert to speak instead. In his 20-minute speech, he spoke about efforts that local police could take quickly to help find missing children and how the media could facilitate those efforts. C.J. Wheeler, a reporter from radio station KRLD, approached the Dallas police chief shortly afterward with Seybert's ideas and launched the first ever Amber Alert.

Williams testified in front of the U.S. Congress in June 1996, asking legislators to create a nationwide registry of sex offenders. Representative Martin Frost, the Congressman who represents Whitson's district, proposed an "Amber Hagerman Child Protection Act." Among the sections of the bill was one that would create a national sex offender registry.

Diana Simone, a Texas resident who had been following the news, contacted the KDMX radio station and proposed broadcasts to engage passers-by in helping locate missing children. Her idea was picked up and for the next two years, alerts were made manually to participating radio stations. In 1998, the Child Alert Foundation created the first fully automated Alert Notification System (ANS) to notify surrounding communities when a child was reported missing or abducted. Alerts were sent to radio stations as originally requested but included television stations, surrounding law enforcement agencies, newspapers and local support organizations. These alerts were sent all at once via pagers, faxes, emails, and cell phones with the information immediately posted on the Internet for the general public to view.

Following the automation of the AMBER Alert with ANS technology created by the Child Alert Foundation, the National Center for Missing and Exploited Children (NCMEC) expanded its role in 2002 to promote the AMBER Alert.

Emergency Alert System

In 1996, the now-CEO of the NCMEC declined to come in and further assist the AMBER Alert when asked to by Bruce Seybert and Richard Hagerman and has since worked actively to see alerts distributed using the nation's existing emergency radio and TV response network, Emergency Alert System.

International adoption

United States

In October 2000, the United States House of Representatives adopted H.Res. 605 which encouraged communities nationwide to implement the AMBER Plan. In October 2001, the National Center for Missing and Exploited Children that had declined to be a part of the Amber Alert in February 1996, launched a campaign to have AMBER Alert systems established nationwide. In February 2002, the Federal Communications Commission officially endorsed the system. In 2002, several children were abducted in cases that drew national attention. One such case, the kidnapping and murder of Samantha Runnion, prompted California to establish an AMBER Alert system on July 24, 2002. According to Senator Dianne Feinstein, in its first month California issued 13 AMBER alerts; 12 of the children were recovered safely and the remaining alert was found to be a misunderstanding.

By September 2002, 26 states had established AMBER Alert systems that covered all or parts of the state. A bipartisan group of US Senators, led by Kay Bailey Hutchison and Dianne Feinstein, proposed legislation to name an AMBER Alert coordinator in the U.S. Justice Department who could help coordinate state efforts. The bill also provided $25 million in federal matching grants for states to establish AMBER Alert programs and necessary equipment purchases, such as electronic highway signs. A similar bill was sponsored in the U.S. House of Representatives by Jennifer Dunn and Martin Frost. The bill passed the Senate unanimously within a week of its proposal. At an October 2002 conference on missing, exploited, and runaway children, President George W. Bush announced changes to the AMBER Alert system, including the development of a national standard for issuing AMBER Alerts. A similar bill passed the House several weeks later on a 390–24 vote. A related bill finally became law in April 2003.

The alerts were offered digitally beginning in November 2002, when America Online began a service allowing people to sign up to receive notification via computer, pager, or cell phone. Users of the service enter their ZIP Code, thus allowing the alerts to be targeted to specific geographic regions.

By 2005, all fifty states had operational programs and today the program operates across state and jurisdictional boundaries. As of January 1, 2013, AMBER Alerts are automatically sent through the Wireless Emergency Alerts (WEA) program.

Canada

Canada's system began in December 2002, when Alberta launched the first province-wide system. At the time, Alberta Solicitor-General Heather Forsyth said "We anticipate an Amber Alert will only be issued once a year in Alberta. We hope we never have to use it, but if a child is abducted Amber Alert is another tool police can use to find them and help them bring the child home safely." The Alberta government committed to spending more than CA$1 million to expanding the province's emergency warning system so that it could be used effectively for Amber Alerts. Other Canadian provinces soon adopted the system, and by May 2004, Saskatchewan was the only province that had not established an Amber Alert system. Within the next year, the program was in use throughout the country.

Amber Alerts may also be distributed via the Alert Ready emergency alert system, which disrupts programming on all radio, television stations, and television providers in the relevant region to display and play audio of Amber Alert information. In 2018, Alert Ready introduced alerts on supported mobile devices. When an alert is broadcast, a distinct sound is played and a link to find more information is displayed onscreen. Currently, there is no way to deactivate Amber Alerts on mobile devices in Canada, even if the device is in silent and/or Do Not Disturb modes, which has provoked controversy. These series of multiple blaring alarms going off in the middle of the night have caused residents to complain, often by calling 911. However, there are concerns that hearing repeated alarms may cause Canadians to ignore the alarm when the system is used to warn of life-threatening emergencies.

British Columbia

Translink, the corporation responsible for the regional transportation network of Metro Vancouver in British Columbia, Canada, displays Amber alerts on all their buses' digital signs reading "AMBER ALERT | Listen to radio | Bus #". Details of the Amber alert information are also available on screens at transit stations.

Quebec

The program was introduced in Quebec on May 26, 2003. The name AMBER alert was then adapted in French to Alerte Médiatique But Enfant Recherché, which directly translates as "Media Alert for Child Recovery". In order to launch an AMBER alert, police authorities need to meet 4 criteria simultaneously and with no exceptions:

1. The missing person is a child under the age of 18.
2. The police have reason to believe that the missing child has been abducted.
3. The police have reason to believe that the physical safety or the life of the child is in serious danger.
4. The police have information that may help locate the child, the suspect and/or the suspect's vehicle.

Once all 4 conditions are met, the police service may call an AMBER alert. Simultaneously, all of Quebec's Ministry of transport message boards will broadcast the police's messages. The Société de l'assurance automobile du Québec (SAAQ) road traffic controllers also help with the search. Television and radio stations broadcast a description of the child, the abductor and/or the abductor's car. On the radio, the information is broadcast every 20 minutes for two hours or less if the child is found. On the television, the information is broadcast on a ticker tape at the bottom of the screen for two hours with no interruptions. After this, the ticker tape is withdrawn, but the police continue to inform the public through the usual means of communication.

Over the years, the program gathered more partners in order for the alert to be communicated on different media platforms. As in Ontario, lottery crown corporation Loto-Québec puts to the disposition of the police forces their 8500 terminals located throughout the province. Some of these terminals are equipped with a screen that faces the customer which makes it the largest network of its kind to operate in Canada. The technology employed enables them to broadcast the message on the entire network in under 10 minutes. In addition, The Canadian Wireless Telecommunications Association (CWTA) offers to most Canadians, upon free subscription, the possibility to receive, via text message, on their mobile devices AMBER alert notices.

Ontario

Ontario furthered its reach beyond media and highway signs by offering Amber Alerts on the province's 9,000 lottery terminal screens.

After the abduction and murder of Victoria Stafford, an online petition was started by Suzie Pereira, a single mother of 2 children who gathered over 61,000 signatures, prompting a review of the Amber Alert. There was some concern regarding the strict criteria for issuing the alerts – criteria that were not met in the Stafford case – that resulted in an alert not being issued. Ontario Provincial Police have since changed their rules for issuing an alert from having to confirm an abduction and confirm threat of harm, to believe that a child has been abducted and believe is at risk of harm.

Mexico

Mexico joined international efforts to spread the use of the AMBER alert at an official launch ceremony on April 28, 2011.

Australia

The Australian state of Queensland implemented a version of the AMBER Alerts in May 2005. Other Australian states joined Queensland in Facebook's Amber Alert program in June 2017.

Europe

Logo AMBER Alert Europe

AMBER Alert Europe is a foundation that strives to improve the protection of missing children by empowering children and raising awareness on the issue of missing children and its root causes. AMBER Alert Europe advocates that one missing child is one too many and aims for zero missing children in Europe.

AMBER Alert Europe is a neutral platform for the exchange of knowledge, expertise, and best practices on the issue of missing children and its roots causes. To contribute to a safer environment for children, it connects experts from 44 non-governmental and governmental organisations, as well as business entities from 28 countries across Europe.

Its activities cover prevention and awareness-raising, training, research, and child alerting, as well as launching initiatives aimed at impacting policies and legislation in the area of children’s rights. All activities are implemented in line with the EU Charter of Fundamental Rights and the EU Strategy on the Rights of the Child and with respect for the privacy of children and data protection laws.

Its beginnings

As a response to missing children cases exceeding geographical borders, the AMBER Alert Europe Foundation was founded in 2013 to contribute to better cross-border coordination and cooperation in the search for missing children.

Since then, its network has expanded and now encompasses different experts from a variety of backgrounds who make their know-how and experiences available to improve existing practices and procedures for a fast and safe recovery of children gone missing. Its joint efforts with police experts in the field of missing children even paved the way for a European police expert network in this area.

With the objective to prevent children from going missing, it also develop activities in the area of prevention, awareness-raising, research, and training together with its network of experts.

France

In February 2006, France's Justice ministry launched an apparatus based on the AMBER alerts named Alerte-Enlèvement (abduction alert) or Dispositif Alerte-Enlèvement (abduction alert apparatus) with the help of most media and railroad and motorway companies.

Netherlands

Logo AMBER Alert Netherlands

AMBER Alert Netherlands was launched in 2008. On February 14, 2009, the first Dutch AMBER Alert was issued when a 4-year-old boy went missing in Rotterdam. He was found safe and sound after being recognized by a person who saw his picture on an electronic billboard in a fast food restaurant. He was recovered so quickly, that the transmission of the AMBER Alert was halted before all recipients received it.

An AMBER Alert is issued when a child is missing or abducted and the Dutch police fear that the life or health of the child is in imminent danger. The system enables the police to immediately alert press and public nationwide, by means of electronic highway signs, TV, radio, social media, PCs, large advertising screens (digital signage), email, text messages, apps, RSS news feeds, website banners and pop-ups. There are four key criteria in The Netherlands to be met before an AMBER Alert is issued:

1. The child is (very likely) abducted by an unknown person or persons or the child is missing and its life is in imminent danger
2. The victim is a minor (under 18 years of age);
3. There is enough information about the victim to increase the chances of the child being found by means of an AMBER Alert, such as a photo, information about the abductor or the vehicle used during the abduction;
4. The AMBER Alert is issued as soon as possible after the abduction or disappearance of the child.

United Kingdom

On April 1, 2007, the AMBER Alert system became active in North West England. An implementation across the rest of Britain was planned at that time. This was realized on May 25, 2010, with the nationwide launch of the Child Rescue Alert, based on the AMBER Alert system. The first system in the UK of this kind was created in Sussex on November 14, 2002. This was followed by versions in Surrey and Hampshire. By 2005, every local jurisdiction in England and Wales had its own form of alert system. The system was first used in the UK on October 3, 2012, with regard to missing 5 year-old April Jones in Wales.

Ireland

In April 2009, it was announced that an AMBER Alert system would be set up in Ireland, In May 2012, the Child Rescue Ireland (CRI) Alert was officially introduced. Ireland's first AMBER alert was issued upon the disappearance of two boys, Eoghan (10) and Ruairí Chada (5).

Slovakia

Since April 2015, an emergency child abduction alert system "AMBER Alert Slovakia" is also available in Slovakia. (www.amberalert.sk)

Ukraine

On 22 September 2021, Ukraine's Ministry of Digital Transformation, the National Police of Ukraine and Facebook announced the launch of AMBER Alert in Ukraine.

China

On 15 May 2016, the Ministry of Public Security of the People's Republic of China announced the Ministry of Public Security Emergency Release Platform for Children's Missing Information in Beijing, which was soon rolled out to the rest of the country. It is run by the Criminal Investigation Department of the Ministry of Public Security and receives technical support from Alibaba Group. The platform pushes information of missing children confirmed by the police to the mobile phones of the people around the place where the children disappeared, to mobilise people in the area to find and provide feedback on clues related to abductions, trafficking, and related crimes in the area.

Ecuador

In 2018, Ecuador's Department of Security introduced its own AMBER Alert called EMILIA Alert, named after the abducted girl Emilia Benavides in December 2017.

Malaysia

In September 2007, Malaysia implemented the Nurin Alert. Based on the AMBER alert, it is named for a missing eight-year-old girl, Nurin Jazlin.

Morocco

In March 2023, the General Directorate of National Security of Morocco developed a system in cooperation with Meta Platforms based on the AMBER Alert, named "Tifli Moukhtafi" (lit. 'my child is missing'). The alerts are distributed via SMS and on platforms owned by Meta.

Russia

In 2019, Megafon developed its own alert system called MegaFon.Poisk. It is oriented for all regions of Russia where MegaFon is represented and is used for searches of children and adults as well. For less than half of a year, the service has been used for searching of more than 250 people and in more than 30% of situations people called back with information about a lost person.

Retrieval rate

According to the U.S. Department of Justice, of the children abducted and murdered by strangers, 75% are killed within the first three hours in the USA. Amber Alerts are designed to inform the general public quickly when a child has been kidnapped and is in danger so "the public [would be] additional eyes and ears of law enforcement". As of August 2013, the National Center for Missing and Exploited Children estimates that 657 children have been successfully recovered as a result of the existence of the AMBER Alert program.

A Scripps Howard study of the 233 AMBER Alerts issued in the United States in 2004 found that most issued alerts did not meet the Department of Justice's criteria. Fully 50% (117 alerts) were categorized by the National Center for Missing & Exploited Children as being "family abductions", very often a parent involved in a custody dispute. There were 48 alerts for children who had not been abducted at all, but were lost, ran away, involved in family misunderstandings (for example, two instances where the child was with grandparents), or as the result of hoaxes. Another 23 alerts were issued in cases where police did not know the name of the allegedly abducted child, often as the result of misunderstandings by witnesses who reported an abduction. Seventy of the 233 AMBER Alerts issued in 2004 (30%) were actually children taken by strangers or who were unlawfully travelling with adults other than their legal guardians.

According to the 2014 Amber Alert Report, 186 Amber Alerts were issued in the US, involving 239 children; 60 were taken by strangers or people other than their legal guardians.

Controversies

Crime control theater

Some outside scholars examining the system in depth disagree with the "official" results. A research team led by criminologist Timothy Griffin reviewed hundreds of abduction cases that occurred between 2003 and 2006 and found that AMBER Alerts actually had little apparent role in the eventual return of abducted children. The AMBER Alerts tended to be "successful" in relatively mundane abductions, such as when the child was taken by a noncustodial parent or other family member. There was little evidence that AMBER Alerts routinely "saved lives", although a crucial research constraint was the impossibility of knowing with certainty what would have happened if no alert had been issued in a particular case.

Griffin and coauthor Monica Miller articulated the limits to AMBER Alert in a subsequent research article. They stated that alerts are inherently constrained, because to be successful in the most menacing cases there needs to be a rapid synchronization of several events (rapid discovery that the child is missing and subsequent alert, the fortuitous discovery of the child or abductor by a citizen, and so forth). Furthermore, there is a contradiction between the need for rapid recovery and the prerogative to maintain the strict issuance criteria to reduce the number of frivolous alerts, creating a dilemma for law enforcement officials and public backlash when alerts are not issued in cases ending as tragedies. Finally, the implied causal model of alert (rapid recovery can save lives) is in a sense the opposite of reality: in the worst abduction scenarios, the intentions of the perpetrator usually guarantee that anything public officials do will be "too slow".

Because the system is publicly praised for saving lives despite these limitations, Griffin and Miller argue that AMBER Alert acts as "crime control theater" in that it "creates the appearance but not the fact of crime control". AMBER Alert is thus a socially constructed "solution" to the rare but intractable crime of child-abduction murder. Griffin and Miller have subsequently applied the concept to other emotional but ineffective legislation such as safe-haven laws and polygamy raids. Griffin considers his findings preliminary, reporting his team examined only a portion of the Amber Alerts issued over the three-year period they focused on, so he recommends taking a closer look at the evaluation of the program and its intended purpose, instead of simply promoting the program.

Overuse and desensitization

Advocates for missing children have expressed concerns that the public is gradually becoming desensitized to AMBER Alerts because of a large number of false or overly broad alarms, where police issue an AMBER Alert without strictly adhering to the U.S. Department of Justice's activation guidelines.

The timing of a July 2013 New York child abduction alert sent through the Wireless Emergency Alerts system at 4 a.m. raised concerns that many cellphone users would disable WEA alerts.

Effects on traffic

AMBER alerts are often displayed on electronic message signs. The Federal Highway Administration has instructed states to display alerts on highway signs sparingly, citing safety concerns from distracted drivers and the negative impacts of traffic congestion.

Many states have policies in place that limit the use of AMBER alerts on freeway signs. In Los Angeles, an AMBER alert issued in October 2002 that was displayed on area freeway signs caused significant traffic congestion. As a result, the California Highway Patrol elected not to display the alerts during rush hour, citing safety concerns. The state of Wisconsin only displays AMBER alerts on freeway signs if it is deemed appropriate by the transportation department and a public safety agency. AMBER alerts do not preempt messages related to traffic safety.

Influence

The United States Postal Service issued a postage stamp commemorating AMBER Alerts in May 2006. The 39-cent stamp features a chalk pastel drawing by artist Vivienne Flesher of a reunited mother and child, with the text "AMBER ALERT saves missing children" across the pane. The stamp was released as part of the observance of National Missing Children's Day.

In 2006, a TV movie, Amber's Story, was broadcast on Lifetime. It starred Elisabeth Röhm and Sophie Hough.

A comic book entitled Amber Hagerman Deserves Justice: A Night Owl Story was published by Wham Bang Comics in 2009. Geared toward a young audience by teen author Jake Tinsley and Manga artist Jason Dube, it tells Amber's story, recounts the investigation into her murder, and touches on the effect her death has had on young children and parents everywhere. It was created to promote what was then a reopened investigation into her murder.
