Army investigators said Monday they found no bullet wound or evidence of foul play in the death of a soldier in Afghanistan who died during a Skype video chat with his wife.

Capt. Bruce Kevin Clark collapsed while speaking to his wife on May 1 from his base in Tarin Kot, Afghanistan, southwest of Kabul. His wife, Susan Orellana-Clark, has suggested that Clark was shot, citing a hole visible in the closet behind him that she believed was a bullet hole.
