FOREST HILL, TEXAS  — The Rev. Danny Kirk Sr. greeted everyone walking into his Texas church on Sundays with a big hug and an “I love you.” His weekdays were spent visiting folks in the hospital or mowing lawns and doing household repairs for members in need.

Parishioners, who described Kirk as a dedicated minister with a bubbly personality and a knack for remembering the names of his church’s 800 members, are now looking for answers following his violent death.

Police in the Fort Worth suburb of Forest Hill said Kirk was killed Monday by Derrick Birdow who rammed a car into a wall at his Greater Sweethome Missionary Baptist Church, then chased Kirk and fatally beat him with an electric guitar.

Investigators said they don’t know the motive or if Kirk knew his Birdow, who police subdued by using a taser, but who died after being taken into custody. His name hasn’t been released.
