Hotel questions revised timeline of Las Vegas massacre

The hotel where the Las Vegas gunman was staying when he launched his deadly attack has cast doubt on a revised timeline of events set out by investigators.

Police said earlier this week that they believe Stephen Paddock shot a hotel security guard through the door of his suite on the 32nd floor of the Mandalay Bay hotel six minutes before he unleashed a barrage of bullets into the crowd at an outdoor music festival on the Strip below.
