The man identified as the suspect in Sunday’s mass shooting in Las Vegas was identified the day after as 64-year-old Stephen Craig Paddock. Paddock killed himself by the time police got to his hotel room, but not before killing at least 58 people and injuring more than 500. His death meant little could be ascertained about himself or his motives, though his brother was able to shed some light on the family in an interview.

Paddock’s brother, Eric Paddock, revealed their father was a fugitive from the FBI who robbed banks in the 1960s, according to ABC News. Benjamin Hoskins Paddock was reportedly “psychopathic” and considered suicidal, according to his FBI wanted poster.

“Diagnosed as psychopathic, has carried firearms in commission of bank robberies,” the poster said. “He reportedly has suicidal tendencies and should be considered armed and very dangerous.”

The elder Paddock reportedly went by a number of different aliases including “Old Baldy” and “Chromedome” and at one point robbed $4,600 from the National Bank in Phoenix, according to the New York Daily News. He made his way onto the FBI’s “Most Wanted” list after escaping his 20-year sentence at the Federal Correctional Institution at La Tuna in Texas in 1969.

Paddock’s brother said the two men did not know their father well. He also said that he was shocked when he heard of his brother’s actions.

“There’s nothing more I can say,” he told WFTV. “My brother did this. It’s like he shot us. I couldn’t be more dumbfounded. I don’t understand. It doesn’t make sense.”
