At least 19 weapons found in Las Vegas shooter’s room: Sources

Police have found at least 19 weapons in the hotel room that was used by suspected Las Vegas concert shooter Stephen Paddock.

Two sources familiar with the investigation said that there was a combination of rifles and handguns at the scene, and one of those sources said there were 19 weapons in the room.

Earlier, Clark County Sheriff Joseph Lombardo said there were at least 10 rifles in the room but noted that the investigation was still underway.

No further specifics about the weapons have been confirmed by police.

The Bureau of Alcohol, Tobacco, Firearms and Explosives released a statement announcing that it is “currently conducting an urgent trace on firearms recovered from the scene in Las Vegas.”

The shooting, which took place Sunday night, is the deadliest in modern U.S. history, with at least 58 people killed and about 515 others injured.

John Cohen, a former Department of Homeland Security undersecretary who previously worked as a police officer, said that recordings of the shooting suggest that the shooter used an automatic weapon.

“Listening to the video, it sounds like the weapons were fully automatic,” said Cohen, who is now an ABC News consultant.

He said that when a gun is automatic, that means “you pull the trigger once and rounds are fired in rapid succession.”

“[The bullets] were coming out very quick, and you heard a large number of shots very quickly. That would be very difficult to do with anything other than an automatic weapon,” Cohen said.

“It’s not legal to purchase a fully automatic weapon, but it’s not that difficult to convert legal semiautomatic weapons so that they are fully automatic,” he said.
