LOS ANGELES—The older brother of Las Vegas mass shooter Stephen Paddock was arrested in Los Angeles on Wednesday, October 25 for possession of images of child pornography.

Bruce Douglas Paddock, 58, was detained and taken into custody by authorities at the Valley Village nursing home in North Hollywood where he is a resident.

The  nursing home provides short and long-term care. Before moving into the nursing home, Paddock was homeless, residing illicitly in businesses throughout the area.

According to police, Paddock left behind evidence of child pornography consumption at a Sun Valley business where he had been known to squat and where he was evicted. Authorities began their investigation of Paddock after obtaining evidence and tracking him to the North Hollywood facility.

Los Angeles County Superior Court documents reveal that Bruce is accused of possessing more than 600 pornographic images of children. Ten or more of the images are believed to depict a child younger than the age of 12.

A spokesman for the Los Angeles Police Department revealed that Paddock’s arrest was related to an independent investigation and had no apparent connection to his brother’s shooting rampage in Las Vegas, Nevada on October 1.

This is not Bruce Paddocks first encounter with the law. He was charged with assault and battery in 1989 (which was later dismissed) and in 1993 he was accused of “annoying a child under 18.” He was acquitted on that charge. Prior to Wednesday’s arrest, he faced a criminal offense for a vandalism charge in 2014 where he pled no contest.

Bruce and Stephen are two of four brothers. Their father, Benjamin Hoskins Paddock, was a convicted bank robber who appeared on the Federal Bureau of Investigation’s Most Wanted list.
