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.
Lombardo authorized the release of a lengthy report Friday detailing the movements of Stephen Paddock leading up to the shooting, including his check-in at the Ogden _ a condominium complex _ in downtown Las Vegas, right up to the point officers breached the door of his Mandalay Bay hotel room.
The sheriff had been criticized for not releasing more information on the shooting to the public since mid-October and said the release of such a report was not standard practice.
"This is a unique circumstance," he said.
Lombardo dismissed claims made by a Pennsylvania congressman Thursday that the mass shooting was an act of terrorism or that Islamic State had any hand in the massacre.
"I'd like to see the evidence," he said sharply.
Conspiracies have swirled around the massacre and helped account for tight security at the Police Department's headquarters prior to Lombardo's remarks.
Lombardo said Paddock was the lone gunman.
"There was one shooter in the (Oct. 1) massacre," Lombardo said. "There was only one person responsible, and that was Stephen Paddock."
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.
Paddock's brother, Bruce Paddock, 58, was arrested at a Valley Village nursing home in October in Los Angeles after he was found in possession of child pornography. He was charged with 20 counts of sexual exploitation of a child or possessing child pornography dating to 2014. He has pleaded not guilty.
Friday's report offered more insight into Stephen Paddock.
Investigators who interviewed Danley were told the 64-year-old's demeanor had changed over the past year. According to the report, she said he became "distant" and their relationship "was no longer intimate." She described him as a "germaphobic and having strong reactions to smell."
She also recalled his behaving "strangely" during a September stay at Mandalay Bay. Danley said he kept looking out windows overlooking where the Route 91 Harvest country music concert later was held.
"Paddock would move from window to window looking at the site from different angles," the report said.
Lombardo said the report doesn't answer why Paddock committed the crime, but he still thought a partial explainer may have to do with Paddock's losing large sums of money prior to the shooting. Paddock was a heavy gambler who played video poker. The report showed that he often gambled tens of thousands of dollars at a time.
The sheriff said the department has investigated 1,965 leads, reviewed 21,560 hours of video and obtained more than 251,000 images gathered by the FBI and Las Vegas police. The report also showed there were 529 sightings of Paddock.
Investigators also found four laptop computers and three cellphones in his two Mandalay Bay rooms.
The shooting was the deadliest in modern American history, and Lombardo said 851 people were injured in the attack.
