Victims' family furious as university massacre rifle goes on sale

A woman whose relatives were killed in a 1966 sniper rampage at the University of Texas that left 16 people dead says she is horrified that the high-powered rifle used by the gunman is being sold in an online auction.

Bids are starting at $25,000 for a rifle Charles Whitman used to shoot from the top of a clock tower on the campus in Austin.
