Police say the heroic actions of church members and staff at the CrossPointe Community Church in Wayne stopped a mass shooting on the property Sunday.

A livestream during services captured gunfire and panic when a man armed with a handgun and rifle and wearing a tactical vest hopped out of his truck and started shooting outside the church.

Wayne Police Chief Ryan Strong says a security guard was shot in the leg by the attacker before a churchgoer and security staff were able to intervene.

“A parishioner struck the gunman with his vehicle as the gunman shot the vehicle repeatedly,” he said. “At least two staff members shot the gunman, causing fatal wounds.”

The suspect — identified as 31-year-old Brian Anthony Browning — never made it inside the church, police say. The guard who was shot was treated for non-life-threatening injuries and is expected to be fine. Nobody else was hurt.

The shooting occurred around 11 a.m. in Wayne, a city of about 17,000 people located about 25 miles west of Detroit.

Strong put to rest racist social media speculation about the shooter.

“His motivations are unknown, but at this point, it appears he was suffering from a mental health crisis,” he said. “We are grateful for the heroic actions of the church’s staff members, who undoubtedly saved many lives and prevented a large-scale mass shooting.”

About 150 people were inside the church at the time.

Police executing a search warrant at Browning’s home in Romulus — about 5 miles south of Wayne — found additional rifles, several more handguns and a large amount of ammunition, according to The Associated Press.

Police say Browning had no prior criminal history, but he had attended services at the church a few times in the last year and his mother is a member.
