The man who is the head of security at West Freeway Church of Christ is being praised for his “heroic actions” after he said he shot and killed the gunman who opened fire inside the church Sunday.

“I don’t feel like I killed a human,” Wilson told Blayne Alexander of NBC News. “I feel like I killed an evil. That is how I am coping with the situation.”

Wilson, 71, said that he had his gun out as the shooter turned to the front of the auditorium, but had to wait a second to get a clear shot as members of the church reacted to the attack. The man went down and didn’t get up from the head wound as other congregation members on the security team came in.

In the aftermath of a 2017 shooting at a church in Sutherland Springs, Texas, that left 26 people dead, state lawmakers passed new legislation allowing for armed church security teams.
