DALLAS--A gunman wearing a wig and fake beard raised immediate suspicion when he walked into a church service in Texas before opening fire with a shotgun and killing two people, a volunteer security member who shot the assailant said on Monday.
The victims of Sunday's shooting, identified as Anton Wallace, 64, of Fort Worth and Richard White, 67, of River Oaks, were also members of the security force at West Freeway Church of Christ, the state's attorney general said.
Jack Wilson, the head of the security detail, fired a single shot that took down the gunman, identified as Keith Thomas Kinnunen, 43, of River Oaks.
Wallace was serving communion at the church in the Fort Worth suburb of White Settlement and was approached twice by Kinnunen in the moments before the gunfire rang out. "When he sat back down the second time, shortly after that, he stood up, turned, and produced a shotgun," Wilson told NBC News.
Wilson and White began "drawing our weapons. Richard did get his gun out of the holster. He was, I think, able to get a shot off, but it ended up going into the wall. The shooter had turned and shot him and then shot Tony and then started to turn to go towards the front of the auditorium," Wilson told NBC. "I fired one round. The subject went down."
Kinnunen was not a regular at the church and immediately raised suspicion when he walked in with the wig and fake beard that he kept adjusting, Wilson said.
The reason for Kinnunen's actions are unclear. State Attorney General Ken Paxton told a news conference that the gunman may have been mentally ill, but authorities were investigating a possible motive.
Local TV station NBC DFW, citing unidentified law enforcement sources, said Kinnunen had a criminal record that included charges of aggravated assault with a deadly weapon in 2009. A Texas Department of Public Safety spokeswoman declined to comment.
Texas allows concealed carry in places of worship under a new law that took effect in September. It was passed in the wake of a shooting at the First Baptist Church in Sutherland Springs, Texas, in 2017 that killed 26 people.
Paxton encouraged other states to allow citizens to carry concealed weapons for defense in case of active shooters. Wilson had previously trained other churchgoers to use firearms, and had his own shooting range, Paxton said.
But gun control advocates and some religious leaders have argued such laws have no place in houses of worship. "Instead of looking for a success story in a tragedy, lawmakers should be talking about how they can prevent gun violence in the first place," said John Feinblatt, president of Everytown for Gun Safety.
