Hotel worker says he warned about shooter before massacre

A maintenance worker said Wednesday he told hotel dispatchers to call police and report a gunman had opened fire with a rifle inside Mandalay Bay before the shooter began firing from his highrise suite into a crowd at a nearby musical performance.

The revised timeline has renewed questions about whether better communication might have allowed police to respond more quickly and take out the gunman before he committed the deadliest mass shooting in modern U.S. history.

Worker Stephen Schuck told NBC News that he was checking out a report of a jammed fire door on the 32nd floor of Mandalay Bay when he heard gunshots and a hotel security guard, shot in the leg, peeked out from an alcove and said to take cover.

“As soon as I started to go to a door to my left the rounds started coming down the hallway,” he said.

That account differs dramatically from the one police gave last week.
