Omar Saddiqui Mateen, the shooter behind worst mass murder in US history, called 911 emergency line around time of attack to pledge allegiance to ISIS and mention the 2013 Boston Marathon bombers, a US official said on Sunday.
However, in an address to the nation on Sunday, President Barack Obama said there was “no precise motivation or inspiration known yet” for the shooter, who killed 50 people and wounded 53 others at a gay nightclub in Orlando, Florida.The shooting is “a reminder of how easy it is for someone to get their hands on a weapon,” he said.
In the past two weeks Mateen legally purchased a Glock pistol, found at the shooting scene, from a gun store in St. Lucie County, Florida, a law enforcement official said.
Mateen, 29, is from Fort Pierce, about 120 miles southeast of Orlando, two law enforcement officials said, and he had been trained as a security guard.
Investigators said members of Mateen’s family said Mateen had expressed anti-gay feelings. Orlando authorities said they consider the crime an act of domestic terror.
