Memory of Murder Forty Eight Hours : Season 20 Episode 7

During the early morning hours of Nov. 15, 2004, Peter and Joan Porco were brutally attacked by an axe-wielding intruder in their bedroom. Peter Porco was murdered, his wife left for dead. Miraculously, she was clinging on to life when investigators and medics arrived at the crime scene hours later. Suffering from severe injuries, police say Joan Porco indicated to them who the killer was with a nod. But as Peter Van Sant reports, she says she has no memory of that. And she says she never would have implicated the person who faced trial for the murder of her husband.
