FBI finds no specific motive in Vegas attack that killed 58

The FBI said as it concluded the investigation of the 2017 massacre that killed 58 country music fans the high-stakes gambler responsible for the deadliest mass shooting in modern U.S. history sought notoriety in the attack, but left his specific motive a mystery. The FBI said while the agency found no "single or clear motivating factor" to explain why Stephen Paddock opened fire from his suite in a high-rise casino hotel, Paddock may have been seeking to follow in his father's criminal footsteps.

The agent in charge of the FBI's Las Vegas office Aaron Rouse told The Associated Press "it wasn't about MGM, Mandalay Bay or a specific casino or venue." "It was all about doing the maximum amount of damage and him obtaining some form of infamy."

Federal agents said Paddock's physical and mental health was declining. The 64-year-old's wealth had diminished, and he struggled with aging. The findings were contained in a long-awaited report compiled by the FBI's Behavior Analysis Unit, a group of experts who spent months examining several factors that might have led to the rampage.
