A Mableton man was arrested Monday and charged with the murder of Acworth Marine Zach Gamble outside a Smyrna party March 25.

Sean DGene Hall, 38, of the 5100 block of Huntscrest Drive was arrested at work in Cherokee County after more than a month of Cobb County police investigation into what happened to Gamble after he attended a friend’s birthday party at the Concord Crossing Apartments the night of March 24.

Gamble, 34, was found lying in the parking lot of the apartment complex about 6 a.m. March 25 after a taxi hit him. The veteran of two tours of duty in Iraq had suffered severe head trauma that had nothing to do with the accident with the cab.

Gamble spent the next two weeks unconscious at WellStar Kennestone Hospital in Marietta before he was taken off life support and died April 8.

Among his survivors is a 7-year-old son, Luke.

Gamble’s family agitated for police to solve his death, including using a Facebook page.

Police detectives now have determined that several people confronted Gamble in the Smyrna parking lot early March 25 after the birthday party, police spokesman Sgt. Dana Pierce said in a news release.

That confrontation resulted in Gamble’s fatal injuries.

Hall is charged with aggravated assault, aggravated battery and felony murder, plus a probation violation, and is being held without bond in the Cobb County jail.

Police continue to investigate and ask anyone with information to call 770-499-3945.

Gamble was a corporate planner and buyer at Uni-Select in Kennesaw. He served in the Marines from 2001 to 2005. He was a graduate of Brandon Hall School in Sandy Springs and Indiana University-Purdue University at Indianapolis.
