The owner of a casino where Stephen Paddock gambled says the Las Vegas gunman didn't drink alcohol or show any signs of trouble when he was a customer there.
Steve Wynn said in an interview on "Fox News Sunday" that Paddock had "the most vanilla profile one could possibly imagine."
He says Paddock didn't run up debts or have a gambling problem. Wynn said butlers, waiters and massage employees knew Paddock and his girlfriend.
Wynn also described some of the security measures his casino put in place in recent years that include magnetometers and training of housekeeping staff to report suspicious actions like a do-not-disturb sign remaining on a door for an extended period of time.
Paddock killed 58 people at a country music festival from his 32nd floor suite at the Mandalay Bay, which is owned by MGM Resorts.
