Las Vegas shooting

The Las Vegas shooter's autopsy didn't shed light on his motive

Autopsy results have been released for Stephen Paddock, the gunman who killed 58 people and wounded about 500 more in a mass shooting in Las Vegas in October.

The autopsy confirmed Paddock died of a self-inflicted gunshot wound and also found he had anti-anxiety medication in his system at the time of his death. Authorities say it did not shed light on his motive for the attack.

"It seems that based on the autopsy reports there were no physical excuses for what Steve did," said his brother Eric Paddock. "We may never understand why Steve did this."
