Bruce Paddock, the estranged brother of Las Vegas mass shooter Stephen Paddock, has been detained by Los Angeles authorities on accusations of possessing child pornography, PEOPLE confirms. Authorities declined to say more about the situation, but a law enforcement source told the Associated Press that the child pornography investigation occurred prior to the shooting in Las Vegas.
The child pornography investigation began prior to Stephen Paddock's shooting rampage on the Las Vegas Strip on October 1 that killed 58 people and wounded hundreds more, the Associated Press reported.
Bruce Paddock was taken into custody in North Hollywood on Wednesday morning, according to a source who was not authorized to speak publicly about the case and requested anonymity. The arrest was reportedly performed by a joint task force including the Federal Bureau of Investigation and the Los Angeles Police Department.
Police say the alleged offences all occurred in an eight-month period, between January 1 and August 30 in 2014.
The hard drive may have contained potential key evidence to Paddock's motive, the report said.
Investigators digging into Paddock's background also learned he purchased software created to erase files from a hard drive, but without the hard drive to examine it is impossible to know if he ever used the software, one source said. Court records show Bruce Paddock has previous convictions for vandalism, criminal threats and theft, according to NBC News.
Bruce Paddock, 59, was arrested on a 20-count felony complaint, a police statement said.
