Panama City police were called to Gillman Marine in Millville around 7 a.m. Monday morning. Witnesses say 45-year-old Herman Harmon shot and killed shop owner Jeffrey Gillman.
Witnesses say Harmon shot Gillman several times with his .38 caliber revolver, then stood back against this fence and waited for law enforcement to arrive.
"He stayed in the area. He didn't try to flee."
Jeff Gillman's longtime friend and co-worker, Buford Taylor, says he arrived to work shortly after Gillman was shot.
Taylor says he kneeled next to Gillman on the gravel and said a final prayer.
Harmon owns Custom Marine Metal Works on Panama City Beach.
Gillman contracted Harmon for welding work. Police aren't giving a motive for Monday's murder, other than to say there was some type of ongoing feud between the two businessmen.
"Sometime last week there was a disagreement between the guy and victim."
Even Gillman's friends and family say they don't know why someone would want to hurt Jeff, and those who knew the gunman say they don't why he would have wanted him dead.
"I always thought he was a level headed, pretty nice guy. I use to work with him building hovercrafts. I couldn't believe he did that."
We spoke briefly to Harmon's wife Monday. She refused to comment on her husband's motive.
Harmon is being held at the Bay County Jail. He is charged with an open county of murder, and is scheduled to appear before a judge Tuesday.
