The FBI said on Tuesday that it failed to find a motive for the mass shooting at a Las Vegas country concert in October 2017, Fox News reported.
The lack of a conclusion comes despite nearly 16 months of investigating the reason that Stephen Paddock shot to death 58 people and wounded scores of others from his hotel room in the Mandalay Resort and Casino, the deadliest mass shooting in modern American history.
Las Vegas police, which finished their investigation in August, also did not establish a motive.
“It wasn't about MGM, Mandalay Bay or a specific casino or venue,” said Aaron Rouse, the special agent in charge of the FBI’s Las Vegas office. “It was all about doing the maximum amount of damage and him obtaining some form of infamy.”
Paddock acted alone when he planned and carried out the attack, Rouse said, adding that he fatally shot himself as police arrived at his hotel suite.
The authorities discovered no suicide note, video, manifesto, or other communication in connection with the attack, according to the Las Vegas Review-Journal.
Paddock was a loner who had no religious or political affiliations and liked to gamble tens of thousands of dollars at a time, according to investigators, Fox News reported.
Authorities said he started stockpiling weapons approximately one year before the attack and spent $1.5 million in the two years before the mass shooting.
He also begun to distance himself from his family and girlfriend, who told authorities that doctors had informed him that he was suffering from an incurable “chemical imbalance.”
