In Too Deep - Updated Forty Eight Hours : Season 23 Episode 20

Laura Hall was like any other college student. She was living in Austin, Texas, whre she attended the University of Texas, dating the guy of her dreams, business student Colton Pitonyak, and planning to go to law school. But on the morning of Aug. 17, 2005, Hall entered into a nightmare when she found a young woman's dead body in the bathtub in Pitonyak's apartment. It was 21-year-old Jennifer Cave, a friend of Pitonyak's. Within days of the murder, authorities nabbed Pitonyak and Hall in Mexico. But while Hall claimed that she went to Mexico against her will, police believed she was helping Pitonyak escape and charged her with hindering apprehension. Even worse, Cave's body had been severely mutilated, stabbed dozens of times and dismembered. At his trial, Pitonyak stunned everyone when he testified that it was, in fact, Hall who dismembered her. Correspondent Maureen Maher updates the case on an all-new "48 Hours Mystery".
