Thirteen Orlando police and Orange County sheriff's deputies opened fire on Omar Mateen in the final gunfight at the Pulse nightclub, OPD's SWAT commander said in an interview Thursday.
Mateen appeared through a hole that was blown open by the bomb squad, and officers opened fire, said Orlando police Capt. Mark Canty.
It's not clear who fired first, or how many shots there were. It is still unknown if any of the hostages were struck by any friendly fire, Canty said.
Officers blew the first hole in the wall between the two bathrooms at about 5:02 a.m. Officers then opened a second hole that was to a bathroom stall, but no one could get out.
