The FBI chief in Nevada says motive behind Las Vegas concert massacre is still a mystery.
Investigators found that Paddock had been losing money for two years and had been showing signs of depression.
Since the shooting, law enforcement officials have been largely quiet about Paddock’s motives and the lack of information has fueled several conspiracy theories.
Paddock was known to play video poker and gamble large sums of money on the machines. He also played at multiple properties on the Vegas Strip as well as casinos in Mesquite and Reno.
