Sept. 29 (UPI) -- The U.S. Army is investigating the suspected suicides of three soldiers who died within a span of 72 hours earlier this month. All three soldiers belonged to the 10th Mountain Division, based at Fort Drum in upstate New York, which described the deaths in a statement as "isolated and unconnected self-harm incidents." The soldiers were identified by Army Times as Staff Sgt. "Immediately when we have a situation when a soldier is suspected of taking their own life, we want to know the trigger," Maj. Gen. Milford H. Beagle Jr., 10th Mountain commander, told Army Times. The deaths came as Fort Drum has highlighted suicide-prevention resources for servicemembers throughout the month of September.
