ATLANTA -- A court appearance is set for a man accused of gunning down a volunteer during a prayer service at a Georgia megachurch.

A preliminary hearing for Floyd Palmer was originally scheduled for Thursday morning, but it was delayed until Friday.

Police say Palmer shot 39-year-old Greg McDowell to death at World Changers Church International Church outside Atlanta in October. McDowell was killed as he led a prayer group. No one else was hurt.

Police records show Palmer was charged more than a decade ago with a shooting outside a Maryland mosque. Palmer was committed to a psychiatric hospital in 2004 after pleading not criminally responsible to the mosque shooting.

Palmer's lawyer, Drew Findling, has said his client's mental competency must be evaluated as the criminal case against him moves forward.
