TAMPA — The MacDill Air Force Base airman who died last week in an apartment off the base committed suicide.
Douglas Caldas, 25, was assigned to the 6th Medical Support Squadron. According to authorities, Caldas had talked about killing himself earlier in the day. When a friend went to his West Shore Boulevard apartment to check on him, he was already dead from stab wounds.
The Hillsborough County Medical Examiner's Office ruled his death a suicide.
The suicide rate of active-duty troops has risen steadily over the past decade, hitting a record of 350 last year. Suicide rates in the Army and Marines surpassed the civilian rate in 2008.
