LAS VEGAS _ Stephen Paddock, the mass shooter who killed 58 people in Las Vegas in October, kept child pornography on his computer and amassed large stockpiles of weapons leading up to the crime, Clark County Sheriff Joe Lombardo said Friday.
Paddock's brother, Bruce Paddock, 58, was arrested in October in Los Angeles for possession of child pornography.
Lombardo also authorized the release of a lengthy report detailing the movements of Stephen Paddock leading up to the shooting, including his check-in at the Ogden in downtown Las Vegas, right up to officers breaching the door at his Mandalay Bay hotel room.
The sheriff had been under fire for not holding a public news conference on the shooting since mid-October and said the release of such a report was not standard practice.
"This is a unique circumstance," he said.
Lombardo also was dismissive of claims made by a Pennsylvania congressman Thursday that the mass shooting was terrorism or that Islamic State had any hand in the massacre. Conspiracies have swirled around the massacre and helped account for tight security at the Police Department's headquarters prior to Lombardo's remarks.
The sheriff also said his department was not looking to bring charges against Marilou Danley, Paddock's girlfriend, who had been named a person of interest in the shooting early in the investigation and was featured prominently in search warrants and affidavits unsealed by a federal judge last week.
The shooting was the deadliest in modern American history, and Lombardo said 851 people were injured in the Oct. 1 attack.
