The Army psychiatrist accused of murdering 13 people in last week’s Fort Hood massacre may have wired money to Pakistan before the shootings and apparently had HIV drugs and other prescription medications in his possession.

Reporters including Fox News camera crews were shown inside the sparse one-bedroom apartment of Major Nidal Malik Hasan, who survived the Nov. 5 rampage and has been talking to investigators since he woke up in the hospital.

Hasan, 39, was charged Thursday with 13 counts of premeditated murder.

Among the items reportedly found in his upstairs apartment: bottles of vitamins and medications stuffed in a shoebox for which Hasan had obtained prescriptions or, in some cases, that he had prescribed for himself.

Combivir, a drug used to treat HIV, was in the stash with about a dozen pills left in the bottle, the Dallas Morning News reported. It had been given to Hasan in 2001 at Lackland Air Force Base in San Antonio, the newspaper said.

It wasn’t known why Hasan had the HIV medication or whether he was taking it. Combivir also has been prescribed to medical workers to prevent exposure to HIV in needles.
