Did Hasan send money to Islamic groups?

WASHINGTON, Nov. 19 (UPI) -- The U.S. Army psychiatrist charged with killing 13 people at Fort Hood donated $20,000 to $30,000 annually to foreign Islamic charities, investigators say.

They also said Major Nidal Malik Hasan may have been worried he would test positive for the HIV virus, ABC News reported. ABC reporters said they found Combivir, a drug used to treat AIDS and sometimes kept on hand by doctors because of the risk of being infected by a needle stick, in his apartment.

A colleague at Fort Hood reportedly told investigators about the AIDS worry.

The investigation has determined Hasan was a strict Muslim with an interpretation of its laws so strict he did not believe in insuring his car. The money he sent to charities came out of a salary of $92,000 a year.

The U.S. government considers some Islamic charities fronts for terrorist groups.

But employees at a strip club in Killeen, Texas, the town next to Fort Hood, said Hasan was a regular there. The club features dancers in the buff.

When Hasan was being trained at Walter Reed Medical Center in Washington, supervisors there said they found him difficult with behavior that was often strange.
