A 19-year-old San Antonio man is in custody after police say he fatally attacked his sleeping father with an ax.
Police say Marshall Lee Giles died of his injuries hours after the attack late Wednesday night.
Police say Giles' son, also named Marshall Lee Giles, was found hiding in the crawlspace under his father's home in downtown San Antonio with a "hatchet with a long handle."
Television station WOAI reports the younger Giles originally was held on a $20,000 bond on an aggravated assault charge but the charge is expected to be upgraded to murder.
A motive for the attack remains under investigation.Copyright 2012 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
