ORLANDO, Fla. — Gunman Omar Mateen, 29, opened fire at a gay nightclub in Orlando early Sunday, leaving at least 49 people dead and 53 wounded before he was killed in a shootout with SWAT team members.

Channel 9 found out that 202 rounds were fired during the Pulse nightclub massacre Sunday, a law enforcement source said. That includes the gun battle between Mateen and law enforcement personnel, the source said.

The FBI's director said the agency is trying to determine whether the nightclub shooter had recently scouted Walt Disney World and other locations as potential targets.

Director James Comey made the comments at a Monday news conference about the deadliest mass shooting in U.S. history. When asked whether Disney and other locations had been reconnoitered, Comey said, "We're still working through that."

He also said he wasn't in a position to comment further.

The Associated Press said that, citing an unnamed federal law enforcement source, reported that Mateen had recently scouted the theme park.

The report said he visited with his wife.

According to the AP, representatives for Walt Disney World didn't immediately return calls seeking comment.
