ATLANTA (AP/WAOK) - The pastor of a Georgia mega-church is seeking to raise nearly a quarter of a million dollars to help a church volunteer who was gunned down inside a chapel.

The Rev. Creflo Dollar on Sunday told members of World Changers Church International that the goal is to raise $234,000 for the family of 39-year-old Greg McDowell.

Police say Floyd Palmer calmly walked into a chapel on the church campus Wednesday, approached McDowell as he led a prayer service and shot him to death. Palmer has been charged with murder. His lawyer didn’t returned phone calls from The Associated Press.

Officials say Dollar said the church aims to erase all debts for McDowell’s family, and urged congregation members to “show the world the power of a mega-church.”
