"BAD BLOOD" ON "20/20 SATURDAY"

Airs April 2, 10 p.m. EDT on ABC

Love, lies and videotape. Shayna Hubers was convicted and sentenced to 40 years in prison last year for the murder of her boyfriend, Ryan Poston. But now, a new development could change everything. "20/20" gets an inside look at the series of unfortunate events that led to the young lawyer's death. Poston, 29, was found shot six times in his condominium, killed with his own gun. Hubers claimed the couple had a violent domestic dispute that resulted in her killing him in self-defense. But later, after a lengthy police interrogation, a different picture emerged, one of a jilted lover who joked to one detective: "I gave him the nose job he wanted." Gio Benitez has those remarkable police interrogation tapes, interviews with the lead investigators and with friends and family of Poston. Now, the surprising twist from the life of a juror that could lead to a new trial for Hubers.

"20/20 Saturday" airs SATURDAY, APRIL 2 (10:00-11:00 p.m. EDT) on the ABC television Network.

"20/20" is anchored by Elizabeth Vargas and David Muir. David Sloan is senior executive producer.
