Omar Mateen of Fort Pierce identified as Pulse Nightclub killer
Senator Bill Nelson says the gunman in the Pulse Nightclub shooting, identified by multiple agencies as Omar Mateen, is from Fort Pierce. The FBI confirmed his identity during a news conference Sunday afternoon.
A source told CNN Mateen called 911 before the shooting and claimed allegiance to ISIS.
Police evacuated the Woodland Condominium complex at 2517 South 17th Street in Fort Pierce, possibly in connection with the investigation.
Authorities also entered a home on Bayshore Boulevard in Port St. Lucie Sunday afternoon, apparently in connection with the nightclub shooting that left 50 people dead.
St. Lucie County Sheriff Ken Mascara said his office is working with federal state and local partners to "determine any nexus that might exist between our local area and the circumstances surrounding the incident."
Mateen, born in 1986, is a U.S. citizen.
Friends who knew him spoke to CBS12 reporter Cory Pipping, calling Mateen "a quiet and relaxed person." The two friends told CBS12 they met Mateen at parties about five years ago.
Nelson said the attack, based on intelligence briefings, may have connections to ISIS and Islamic radicalism. Nelson is asking people who knew Mateen to contact the FBI.
Police haven't officially released the gunman's name.
Both of Mateen's parents are originally from Afghanistan, according to CBS News.
According to online records, Mateen was married in 2009.
CNN reported he worked as a private security guard.
CBS News confirmed Mateen worked at G4S USA, a security firm in Jupiter.
The nightclub shooting left 50 dead and more than 53 people wounded.
The shooting happened just after 2 a.m. at the club. Police exchanged gunfire with the suspect outside the club.
The shooting is under investigation as an act of domestic terrorism.
The suspect went back into the club, armed with an assault-style rifle, a handgun, and "some kind of device," police said, and remained holed up for three hours.
SWAT members entered the club to rescue the hostages around 5 a.m. Officers exchanged gunfire with the suspect who ultimately died.
Orlando Police called it a "tragedy for officers" as well, saying the shooting scene left many veteran officers "shaken."
The Treasure Coast is no stranger to terrorism. The first American suicide bomber in Syria was Moner Mohammad Abu Salha of Fort Pierce. And, a number of the 9/11 hijackers trained at a number of flight training facilities in our viewing area.
The FBI said late Sunday Mateen was under investigation in 2014 for having ties to Abu Salha, also of Fort Pierce.
