Omar Mir Seddique (November 16, 1986 - June 12, 2016), also known as Omar Mateen, was an American mass murderer who killed 49 people and wounded 58 others in a mass shooting at the Pulse gay nightclub in Orlando, Florida, on June 12, 2016, before he was killed in a shootout with the local police. It was both the deadliest shooting by a single shooter and the deadliest act of violence targeting LGBT people in United States history.

Before the shooting, he had been investigated for connections to terrorism by the Federal Bureau of Investigation (FBI) in 2013 and 2014. During that period, he was placed on the Terrorist Screening Database, but subsequently removed. In a call to 9-1-1 during the shooting, Mateen identified himself as "Mujahideen", "Islamic Soldier", and "Soldier of God"; and pledged his allegiance multiple times to the militant jihadist group Islamic State of Iraq and the Levant (ISIL). He said the shooting was "triggered" by an airstrike in Iraq that killed Abu Wahib, an ISIL commander, six weeks before.
Mateen was born Omar Mir Seddique on November 16, 1986, in New Hyde Park, New York, to Afghan parents. His father, Mir Seddique Mateen, is a Persian-speaking Pashtun who emigrated from Afghanistan in the 1980s. After being raised in New York for a few years, he moved with his family to Port St. Lucie, Florida, in 1991. His family was described as being moderate Muslims and "an all-American family".
Behavior in schoolEdit
At a young age, Mateen displayed a preoccupation with violence, the Associated Press and The Washington Post reported. For his elementary and middle school education, he attended classes in St. Lucie County, Florida. While at Mariposa Elementary School, a third grade teacher wrote that Mateen was "very active ... constantly moving, verbally abusive, rude, aggressive ... much talk about violence & sex ... hands all over the place – on other children, in his mouth". In the seventh grade, Mateen was moved to a separate class with the purpose of avoiding "conflicts with other students" and suffered from poor scholarly performance due to "many instances of behavioral problems".
A classmate at Mariposa said that Mateen was a bully, disrespectful to girls and acted like he was better than his classmates. Another classmate reported that Mateen was bullied at school because of his weight and his Afghan heritage. His parents were described as "dismissive" of his poor behavior while his father "had a reputation for being disrespectful of female teachers and dismissive of complaints about his son". In 1999, while Mateen was in the eighth grade, his teacher sent a letter to his father regarding an "attitude and inability to show self-control".
Mateen began his secondary education at Martin County High School in 2000, and at the age of 14 was expelled after being in a fight in math class, where he was briefly arrested without being handcuffed and charged with battery and disrupting school, though the charges were later dropped. While a sophomore attending Spectrum, an alternative high school for students with behavioral issues, classmates told The Washington Post that Mateen cheered in support of the hijackers during the September 11 attacks and that he stated that Osama bin Laden was his uncle who taught him how to shoot AK-47s, all of this before knowing that bin Laden was the mastermind of the attacks. After his outburst, Mateen's father arrived at the school to pick him up and slapped him in the face, with Mateen later being suspended for five days after the incident. Soon after the September 11 attacks, "he shocked other students on his school bus by imitating an exploding plane", reported The New York Times.
A retired dean of Martin County High School, Dan Alley, said that they "tried to counsel him and show him the error of his ways, but it never had the effect that we were hoping for," and that his father "would not back up the school, and he would always take his son's side". Mateen was later sent to St. Lucie West Centennial High School after getting into a fight with a student. By the time Mateen had returned and graduated from Martin County's Stuart Adult Vocational School in 2003, he had been suspended for 48 days for being involved in fights and injuring other students.
Post-secondary education and employmentEdit
Mateen attended Indian River State College's Criminal Justice Training program and in a questionnaire, he admitted to committing or being involved in a crime that went undetected, but did not provide specific details. He went on to earn an associate of science degree in criminal justice technology from the college in 2006. He worked in a number of local stores and restaurants while attending school.
In October 2006, Mateen began working as a recruit for the Florida Department of Corrections, being assigned to the Martin Correctional Institution. In a letter explaining his juvenile record as part of his successful application, Mateen explained the incident of when he was arrested at school when he was fourteen. He also wrote that he had experimented with marijuana as a young teenager. Following the Virginia Tech shooting in April 2007, Mateen suggested in a corrections officer training class that he would bring a gun to class. P.H. Skipper, who was the warden at the institution, wrote that "in light of the tragic events at Virginia Tech officer Mateen's inquiry about bringing a weapon to class is at best extremely disturbing". Days later on April 27, 2007, Mateen "was involuntarily dismissed" from the program and never became a certified corrections officer.
G4S said two screenings of Mateen—one conducted upon hiring and the other in 2013—had raised no red flags. Under Florida state law, for him to work as an armed guard the company was required either to make a full psychiatric evaluation of Mateen, or to administer a "validated written psychological test". The test administered was the updated Minnesota Multiphasic Personality Inventory (MMPI-2), a test used for job screenings and court cases requiring those subjected to it to agree or disagree with statements such as "My soul sometimes leaves my body" and "Once in a while I think of things too bad to talk about." Carol Nudelman, the psychologist listed on the character certification submitted by G4S to the state said she stopped working for the company in 2005. After the shooting, Nudelman, who was said to have evaluated and cleared Mateen for his firearms license in 2007, according to the records of the security company G4S, denied ever meeting him or having lived in Florida at the time, and said she had stopped her practice in Florida in January 2006. G4S said Mateen was not actually interviewed by a psychologist, but rather, a psychologist evaluated the results of a standard test used in job screenings and his test was evaluated by the firm that bought Nudelman’s practice, Headquarters for Psychological Evaluation, owned by Dr Joanne Bauling. G4S said this was a "clerical error." On September 10, 2016, the Florida Department of Agriculture and Consumer Services fined G4S $151,400 for providing inaccurate psychological testing information after it found the psychologist whose opinion was necessary to permit Mateen to carry a weapon was not practicing as a screener. Between 2006 and 2016, 1,514 forms were submitted erroneously listing Nudelman’s name. Mateen's form was among those investigated. He had taken the MMPI-2 and Dr. Syed Shafeeq Rahman, who had close ties with Mateen's family, gave him a medical clearance. G4S admitted Mateen's form had a "clerical error", and clarified that he had instead been cleared by Rahman, who was from the same firm that bought the wrongly named doctor's practice. Rahman had not interviewed Mateen, but evaluated the results of a standard test used in the screening he undertook before being hired.
Nonetheless, G4S removed Mateen from his job post at a courthouse because of threats he made towards coworkers, including one threat where he claimed he would have al-Qaeda kill a deputy's family. Mateen had claimed that his coworkers and courthouse deputies were making racist comments towards him. Despite this, G4S "kept Mateen as an employee" but moved him "to a kiosk at a gated community in Palm Beach County." They never informed the community or its property management company about why he was transferred there.
Mateen held an active concealed carry permit and an armed security guard license. It was also noted that Mateen had no adult criminal record. According to licensing records, he was a proficient shooter who scored at or above the 98th percentile with a 9mm semiautomatic pistol.
In 2010, he was videotaped while working security for a site related to the BP oil spill. Mateen said of those working on the cleanup: "Nobody gives a shit here. Everybody's just, get out to get paid. They're like hoping for more oil to come out and more people to complain so they'll have jobs. They want more disaster to happen." Video of his comments were included in a 2012 documentary, The Big Fix.
In April 2009, Mateen married his first wife, an Uzbekistan-born woman whom he met in 2008 through Myspace, a social networking site. They separated after four months and divorced in July 2011.
Mateen visited Saudi Arabia for an eight-day trip in 2011 and a ten-day trip in 2012. The latter was organized by the Islamic Center at New York University. It included twelve New York City police officers and groups from Columbia and Yale and visited Mecca and Medina. Around these times, he went to the United Arab Emirates. FBI Director James Comey said Saudi officials helped investigate Mateen's trips. In June 2016, the House Intelligence Committee said that U.S. investigators "are searching for details about the Saudi Arabia trips."
In 2011, Mateen met his second wife, Noor Salman, on an online dating site, and the two married shortly afterward. She moved into Mateen's Fort Pierce home in November 2012. She grew up in Rodeo, California, the daughter of Muslim Palestinian Arab immigrants. By September 2013, they were living in a house in Port St. Lucie with Mateen's father and another relative. She reportedly left Mateen and joined relatives in Rodeo, California, by December 2015. At the time of his death, Mateen had a three-year-old son with his second wife.
At the time of the shooting, he lived about 100 miles (160 kilometers) from Orlando, Florida, in Fort Pierce, but received mail at his parents' home in nearby Port St. Lucie. According to Florida Department of Law Enforcement records, he had no criminal record in Florida.
Mateen's father, Mir Seddique Mateen, who hosted a TV show called Durand Jirga Show on satellite television network Payam-e-Afghan in 2015 in which he represented himself as a candidate for the President of Afghanistan, and who has expressed gratitude towards the Taliban, said of his son's actions, "This had nothing to do with religion." He was quoted as saying that he had seen his son get angry after witnessing a gay couple kiss in front of his family at the Bayside Marketplace in Miami months before the attack, which he suggested might have been a motivating factor.
Following the nightclub attack, Mateen's ex-wife told media outlets that during their marriage, Mateen was mentally unstable, and would beat her and keep her completely separated from her family. She also said that he was bipolar, though he had never been given that diagnosis, and had a history of using steroids. Mateen's second wife also said that Mateen became physically and verbally abusive towards her six months into their marriage, though she noted him being kinder in the weeks leading up to the shooting. A former high school student told the Washington Post that he witnessed 15-year-old Mateen on the day of the September 11 attacks being physically assaulted by his father, Mir Seddique Mateen, in front of other students.
Imam Shafiq Rahman at the Fort Pierce Islamic Center told reporters that Mateen would come to the mosque "three or four times a week" with his father and his three-year-old son as recently as two days before the shooting, and said, "He was the most quiet guy. He would come and pray and leave. There was no indication at all of violence." Rahman added that he did not preach violence toward homosexuals.
A former coworker who worked with Mateen in a gated community in western Port St. Lucie described him as "unhinged and unstable". He also said that he frequently made homophobic, racist, and sexist comments, and talked about killing people. The coworker stated he complained to G4S about Mateen "several times"; another co-worker told The New York Times Mateen made people wait at the gate for a number of reasons, including "if it was time for him to do his prayers." A resident who had lived at the community since 2011 described Mateen as "very polite" and "a very nice, positive person", however, another customer said Mateen "acted like a straight-up predator."
Several people who knew Mateen have speculated that he might have been gay or bisexual. A male friend of his from 2006, when the two were in police academy together, said that Mateen went to gay clubs with him and that Mateen once expressed an interest in dating him. Club-goers also recalled Mateen dancing with another man. One classmate, who asked not to be identified by name, said Mateen asked him if he was gay. The FBI has investigated many of these claims but has not found reasonable evidence to establish Mateen's sexual orientation.
After the shooting, the Orlando Sentinel and The Palm Beach Post reported that at least five regular customers at the Pulse nightclub had seen Mateen visit the venue on at least a dozen occasions. Sometimes Mateen drank in a corner by himself "and other times he would get so drunk he was loud and belligerent." A witness, who recognized Mateen outside the club an hour before the shootings, told investigators that Mateen had been messaging him for about a year using a gay dating app called Jack'd. He gave his phone to the FBI for analysis, along with his login details for the application. A third witness said that Mateen had tried to pick up men at the nightclub. Dozens of other witnesses, however told the Tampa Bay Times that they had never seen Mateen at the nightclub. A spokesperson for Barbara Poma, the owner of the Pulse nightclub, called the statement that Mateen had been a regular patron "untrue and totally ridiculous".
Mateen's father Seddique denied that his son was closeted, saying, "If he was gay, why would he do something like this?" Two days later, after multiple reports questioned whether Mateen was homosexual, Mateen's father said, "I didn't see any of it and I don't believe that was the case." However, during an interview with the Brazilian television station SBT Brazil, Mateen's ex-wife claimed that his father called him gay while in her presence. Following the shooting, Mateen's father stated, in an online video in his native language, Dari: "In this month of Ramadan, the gay and lesbian issue is something that God will punish", though "the servants of God shouldn't have anything to do with it."
The Wall Street Journal reported Mateen's ex-wife as saying that "[he] did feel strongly about homosexuality". When asked if Mateen was gay, his ex-wife said she "didn't know" and recalled that he had confessed to going to nightclubs. Gawker reported that his ex-wife's fiance, Marco Dias, told Brazilian media in Portuguese that she had told him that Mateen had "gay tendencies". He also added that his family and others believed he was gay, and that "the FBI asked her not to tell this to the American media".
Investigation into claimsEdit
On June 16, The New York Times reported that the FBI was skeptical of reports that Mateen was "gay but 'closeted'" and that he had made use of homosexual bars or apps. On June 18, the same source added that "federal officials say they have found no evidence in his effects or online presence to back them up." On June 23, the Los Angeles Times reported that the FBI has found no evidence "to support claims by those who say Mateen had gay lovers or communicated on gay dating apps." Investigators consider at least one claimant of homosexual relationships with Mateen not "credible": a man who self-identified as Mateen's lover-of-two-months, "Miguel", had said that he believed the massacre was out of revenge against Latino men when Mateen learned he may have been exposed to HIV from a Puerto Rican man with whom he had sex, but Mateen's autopsy results confirmed that he was HIV-negative.
On June 25, The New York Times reported that after exhaustive investigation with help from the FBI, the gay dating network Adam4Adam concluded that Mateen had never used its app. With regard to reports of Mateen using its and other dating sites and apps for gay men, an Adam4Adam spokesman said, "I think it was a hoax." Furthermore, the article stated that after 500 interviews, the FBI has not found any evidence of homosexuality "through (Mateen's) web searches, emails or other electronic data". The FBI, however, "has found evidence that Mateen was cheating on his wife with other women".
Attorney General Loretta Lynch is on record as saying of Mateen: "I do not want to definitively rule out any particular motivation here." She later added, "It's entirely possible that he had a singular motive. It's entirely possible that he had a dual motive."
The FBI investigated Mateen in May 2013 after he made "inflammatory" remarks while working as a security guard. Mateen had told his coworkers that his family was linked to al-Qaeda and that he had joined Hezbollah, both rivals of the Islamic State of Iraq and the Levant (ISIL) and of one another. Mateen pledged allegiance to ISIL during his 2016 shooting. FBI Director James Comey commented on the contradictions within Mateen's statements. The FBI interviewed Mateen twice after opening an investigation; in these interviews, Mateen admitted to making the statements but "explained that he said them in anger because his co-workers were teasing him." After 10 months, the investigation was closed and Mateen determined not to be a threat. Mateen had been placed on a terrorist watch list while the investigation was under way, but he was removed from it afterwards. Mateen came to the FBI's attention again in July 2014, when he was linked to Moner Mohammad Abu Salha, an American who had traveled to Syria and committed a suicide bombing in late May 2014. The two had been acquainted and "attended the same mosque." The investigation continued, but focused on Abu Salha rather than Mateen, law-enforcement officials told The Wall Street Journal.
U.S. Representative Adam Schiff, the ranking Democratic member of the House Intelligence Committee, said that according to the Department of Homeland Security, Mateen had pledged allegiance to ISIL, though analysts noted that "at this point, it's anyone's guess as to how involved Omar Mateen was with either Al Qaeda or ISIL." Mateen had also pledged support for a suicide bomber who claimed to represent the al-Nusra Front, a Syrian branch of al-Qaeda and an opponent of ISIL. After Mateen's attack, the FBI determined his computer had been used to watch extremist videos, including beheadings, and "to seek information on Islamic State." His wife knew he watched the jihadist videos, "but she did not think much of it because the F.B.I. seemed to have cleared him." A survivor of the shooting said Mateen talked about wanting the United States to "stop bombing my country" and confirmed that Mateen pledged allegiance to ISIL.
Role in the Orlando nightclub shootingEdit
Before the shootingEdit
Two months before the attack, Mateen transferred his share of a Port St. Lucie home for only $10 to his sister and brother-in-law.
Mateen legally purchased a Sauer SIG MCX semi-automatic rifle and a 9mm Glock 17 handgun, the two firearms later used in the shooting, from a gun shop in Port St. Lucie two weeks before the shooting. He also attempted to purchase body armor, but was unable to do so as the store where he tried to make the purchase did not sell the product he sought. A few weeks before the attack, he attempted to purchase body armor and 1,000 rounds of bulk ammunition at another gun shop, but the staff became suspicious of him and turned him away. A salesperson at the shop then said he contacted the FBI, but federal officials said they had no record of such a report, and the local sheriff's office also said it was unaware of the incident.
Officials briefed on the investigation also stated that Mateen went to an unspecified Walt Disney World theme park with his wife. He visited both Disney Springs, where security is less strict than at Disney theme parks, and Pulse between June 1 and 6 during the Gay Days 2016 celebrations at Disney World and in the Orlando area.
NBC News reported that Mateen's second wife told the FBI she "drove him once to the gay nightclub, Pulse, because he wanted to scope it out". An official involved with the investigation told the Associated Press that authorities believed she knew about the plot beforehand, but were reluctant to charge her based only on this suspicion. Days before the shooting, she had accompanied Mateen on a trip to buy ammunition and warned him the evening before the event against anything that he might be planning.
An imam for a mosque in Kissimmee said Mateen prayed there with his wife and child during the week preceding the shooting. He released video footage showing what appeared to be Mateen on June 8, four days before the shooting, praying for about ten minutes.
Hours before the attack, Mateen stopped by his parents' home to visit his father, who said he did not notice anything strange about his son during the visit. That same day, he gave his second wife $1,000 and allowed her to visit her mother in California.
ABC News and Fox News reported that on the early morning of June 12, the day of the attack, Mateen posted on one of his Facebook accounts: "The real muslims will never accept the filthy ways of the west ... You kill innocent women and children by doing us airstrikes..now taste the Islamic state [sic] vengeance" as well as "America and Russia stop bombing the Islamic state." His final post to Facebook was "In the next few days you will see attacks from the Islamic State in the usa." These posts, since deleted, were uncovered by the United States Senate Committee on Homeland Security and Governmental Affairs.
Shooting and deathEdit
At approximately 2:00 a.m. on June 12, 2016, Mateen entered the Pulse nightclub in Orlando, Florida, and began shooting. At 2:22 a.m., he made a 9-1-1 call in which he pledged allegiance to ISIL; referenced Tamerlan and Dzhokhar Tsarnaev, the Boston Marathon bombers; and mentioned Moner Mohammad Abu Salha, an acquaintance of his who died in a suicide bombing in Syria for the Al-Nusra Front in 2014. According to FBI officials, Mateen made two other 9-1-1 calls during the shooting. He also called News 13 of Orlando and identified himself as the nightclub shooter; The Washington Post reported that "he had carried out the Pulse attack for the Islamic State".
Mateen took hostages after police arrived and engaged in a gunfight with him. At approximately 5:00 a.m., police shot and killed Mateen, ending the shooting. A total of 49 people were left dead along with Mateen and 53 others were injured. Mateen was reported to have fired at least 110 rounds during the entire event. The attack was the deadliest mass shooting by a single gunman in United States history,[a] the deadliest incident of violence against LGBT people in U.S. history,[b] and the deadliest terrorist attack in the U.S. since September 11, 2001.
After the shooting, Mateen was eventually buried in the Muslim Cemetery of South Florida, in Hialeah Gardens. An autopsy found that Mateen was shot eight times by police in the head, chest, abdomen, calf, feet, and toe. The bullets, fired from a short distance, went through and through from front to back, suggesting Mateen was shot while facing officers. Several lacerations and "blunt-force injuries", such as bruising and scrapes to his torso, were found, though the origin of these wounds were made unclear. No alcohol or illegal drugs were detected in his system.
Mateen's second wife, Noor Salman, was arrested at her home in the San Francisco Bay Area, on January 16, 2017. The FBI believed she was not truthful with them when questioned following the shooting. She was charged with aiding and abetting as well as obstruction of justice and was scheduled to be arraigned in court in Oakland, California. She pleaded not guilty on January 18, 2017.
