He owns three planes.
Could have used those as weapons and killed much more than 59....
He was trying to kill more then 59. If the police and hotel security had not located his room in 15 to 20 minutes, he would have.
Just my thoughts. Not much of a killing for a millionaire, or was it messaging about guns?
He wounded another 500, so his total casualty count is over 550 people. That kind of casualty rate is generally only reserved for large bombs in crowded places.
