DALLAS (AP) — The congregation at a Texas church where two people were fatally shot had repeatedly given food to the gunman, according to the pastor, but had declined to give money to him, angering a man who a court  deemed mentally incompetent for trial in 2012.

It’s unclear whether Keith Thomas Kinnunen’s extensive criminal record and psychological history would have barred him from legally buying the shotgun he used during Sunday’s attack at the West Freeway Church of Christ in the Fort Worth-area town of White Settlement.

Kinnunen, 43, shot worshippers Richard White and Anton “Tony” Wallace in the sanctuary before a member of the church’s volunteer security team shot and killed him, according to police and witnesses.

Minister Britt Farmer recognized Kinnunen after seeing a photo of him without the fake beard, wig, hat and long coat he wore as a disguise to the service.

Kinnunen visited the congregation several other times this year and was given food but denied money, the minister said.

“We’ve helped him on several occasions with food,” Farmer said in the interview. “He gets mad when we won’t give him cash.”

Farmer declined to speak to The Associated Press on Tuesday.

Authorities have said Kinnunen’s motive remains under investigation and they declined to comment on how he obtained the gun he used, though a Bureau of Alcohol, Tobacco, Firearms and Explosives spokeswoman said it had successfully traced the weapon.
