Documents filed in court have revealed details about the motive behind the deadly shooting at Georgia's Fort Eisenhower over the weekend.

Saturday's shooting triggered a lockdown at the U.S. Army base for hours and ended with an Army reservist dead and a soldier in custody.

Officials say the shooting came after the suspected gunman found another man in the bed of his ex-girlfriend and mother of his child.
His ex-girlfriend? Clearly she was well rid of him. And possibly he of her, too. But he has no business reacting so once they’re no longer an item.
