Investigators have still not determined the cause of death of an Army captain who collapsed while Skyping with his wife, though they said on Monday that no foul play was suspected. Capt. Bruce Kevin Clark, 43, was found dead two hours after he fell forward on his computer while video chatting with his wife, who said she saw what appeared to be a bullet hole on the wall behind him. But investigators found no trauma on his body beyond a possible broken nose likely caused by the blow of falling on his face. Officials are still awaiting toxicology and autopsy results for Clark, who was stationed in Kandahar, Afghanistan.
