SAN ANTONIO -- A homeless man in his 50s was fatally beaten Sunday night because he was panhandling, police said.

The man, who is described as a white male, was found beaten at 8:30 p.m. in the 1900 block of North St. Mary's Street, police said.

He suffered serious head injuries and was dead on arrival at Brooke Army Medical Center, police said. The victim is being listed as a John Doe at the Bexar County Medical Examiner's Office until someone comes forward to report a man missing with the victim's description.

It appeared the victim was intoxicated and was asking for money when he was beaten, police said.

Investigators have very little information to go on.
