A BEAUTIFUL MOM WAS BRUTALLY MURDERED WHILE HER HUSBAND WAS AT WORK - WAS SOMEONE STALKING HER IN LAS VEGAS?

48 HOURS Investigates in "Vengeance in Vegas"

Saturday, July 23 at 10:00 PM, ET/PT

Peter Van Sant and 48 HOURS investigate the death of a beautiful mom who was brutally murdered after her shift as a casino cocktail waitress in Las Vegas, in an encore of "Vengeance in Vegas," to be broadcast Saturday, July 23 (10:00 PM, ET/PT) on the CBS Television Network.

In the early-morning hours of Sept. 29, 2012, Shauna Tiaffay checked out of her job as a cocktail waitress at the Palms Casino Hotel and headed home. When she got there someone was waiting for her-- someone who brutally beat the 46-year-old mother of a young girl to death with a hammer. At the time, her husband George Tiaffay, a West Point Military Academy grad and Las Vegas firefighter, was at work. The murder shocked the community and put co-workers on edge.

Police, as usual, turned to the husband, who had a solid alibi. However, 48 hours into the investigation, detectives got a tip from William Pennix, who had been working in Las Vegas for years as a maintenance man at an apartment complex. Pennix told police he got a call from a friend who told him he had just killed a woman. The tip led investigators to a man nicknamed "Greyhound" and then into the desert for clues. But did the tip lead to the killer?
