Investigators believe the suspected Pittsburgh synagogue shooter, Robert Bowers, acted alone in Saturday’s attack that killed 11 people, according to Robert Jones with the FBI.
Jones says there is no evidence to suggest Bowers had an accomplice.
Investigators recovered three Glock handguns and an AR-15 assault rifle at the Tree of Life synagogue, US Attorney Scott Brady said.
Bowers is accused of killing 11 people and injuring two in his shooting spree at the synagogue. In addition, four police officers responding to the scene were injured during the exchange of gunfire.
Jones praised as heroic the actions of police and SWAT officers who responded.
"Had he made it out of that facility, there is a strong possibility that additional violence would have occurred," he said.
Bowers is scheduled to make his first court appearance on Monday at 1:30 p.m.
