Sister's Warning: Estranged Husband Top Suspect in 'Family Feud' Murder.

Rebecca Bliefnick, a nurse from Illinois, texted her sister that her estranged husband, Timothy Bliefnick, should be the "No. 1 person of interest" if something happened to her. The couple was going through a bitter divorce and fighting for custody of their three children. Timothy Bliefnick, a former "Family Feud" contestant, is accused of breaking into his wife's house and shooting her 14 times. Prosecutors allege that the crime was an act of domestic violence, a claim that Timothy Bliefnick's defense denies. The trial is ongoing.
