The homicide took place Tuesday about 8 p.m. at Rowland’s home on Lemon Street.
Rowland has been charged with one count of murder and one count of possessing a firearm during the commission of certain crimes. He is being held at the Jefferson County Jail awaiting a bond hearing before a Superior Court judge.
Logan was shot at least once and was pronounced dead at the scene, investigators say.
The investigation shows the two men have been arguing for several months over Rowland’s ex-wife, officials said.
The investigation is continuing and the victim’s body is being transported to the GBI crime lab in Augusta for an autopsy.
