, Mateen was a 29-year-old, U.S.-born citizen with parents from Afghanistan. Officials say Mateen was "on the radar" for some time but not the target of any specific investigation. The shooter also held a Florida security officer license and a state firearms license, says TMZ

Ron Hopper, an FBI assistant agent in Tampa, said at a press conference at 7 a.m. this morning that the shooter may have had leanings toward terror groups. "At this time we're looking at all angles right now," said Hopper.
"We do have suggestions that that individual may have leanings towards that, that particular ideology. But right now we can’t say definitively, so we’re still running everything around.”
The mass shooting, which authorities are now calling a "domestic terror incident," has resulted in 50 fatalities and 53 injured, according to ABC News
The shooter involved with Sunday morning's mass shooting at Pulse Nightclub has been identified as Omar S. Mateen of Fort Pierce, of St. Lucie County, Florida.
