A look at the evidence: Two experts disagree on how Col. Michael Stahlman died

On July 31, 2008, Marine Col. Michael Stahlman was found in his quarters in Iraq with a gunshot wound to the head. Mark Reynolds, later hired by the investigating agency NCIS, says the science points to suicide. But Michael Maloney, who, for years, worked for NCIS before the Stahlman incident, is convinced his death was a homicide. Source
