Las Vegas shooter transferred $100K, set up cameras at hotel room

Officials said today that the Las Vegas gunman, Stephen Paddock  transferred $100,000 overseas in the days before the attack and planned the massacre so meticulously that he even set up cameras inside his high-rise hotel room and on a service cart outside his door, apparently to spot anyone coming for him.

Investigators are taking a harder look at the shooter's girlfriend and what she might have known about the attack. FBI is bringing her back to the U.S. on Wednesday for questioning.

The death toll rose to 59 people, not including the shooter.Authorities are still trying to determine Paddock's motive for the deadliest mass shooting in U.S. history.
