Las Vegas police say they don't know what drove a man to rain gunfire on some 22,000 music fans at an outdoor concert last October, an attack that killed 58 people. In an update on the case Friday, Clark County Sheriff Joe Lombardo said there are no signs anyone helped the gunman.
The lack of a motive and any other suspects persisted despite looking into nearly 2,000 leads and sifting through thousands of hours of video, according to Lombardo, citing a preliminary investigation report that was released by the Las Vegas Metropolitan Police Department on Friday (see it below).
"I know and believe there is only one suspect who killed 58 people and injured hundreds more," Lombardo said.
Stephen Paddock, 64, died after carrying out the attack on the night of Sunday, Oct. 1, in which he strafed concertgoers with gunfire from his hotel room on the 32nd floor of the Mandalay Bay casino and hotel. In their report, police say they found no manifesto or suicide note that might help explain why he would set out to murder.
