A maintenance worker said 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 high-rise 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, who had been shot in the leg, peeked out from an alcove and told him to take cover.

Do you think that the hotel might have been more concerned with it's image at the time? Is this worker a reliable source given the fact that over 1000 rounds of ammunition were fired that night by the gunman?
