A man being held in custody in connection with a vehicle driven into a post office early Sunday is reportedly the brother of late NFL star and U.S. Army Ranger Pat Tillman.

The U.S. Postal Service is now leading the investigation and told KPIX-TV that Richard Tillman is the brother of Pat Tillman. U.S. Postal Inspector Matthew Norfleet told the outlet that the motive for the alleged arson is under investigation. Photos from the scene show the words "Viva la me" were spray-painted on the front of the building.

Richard Tillman, a brother of Pat Tillman, faces a hearing in connection with a crash near San Jose, California, that caused a fire at a post office.
