In November of 1994, Farah Fratta was discovered dead in the garage of her Texas home. She had been shot twice in the head. At the time, Farah was in the midst of a divorce with her husband, Bob Fratta. Bob was an upstanding citizen, who worked in public safety as both a police officer and a fireman. But divorce documents were about to make his dark side public. To investigators, Bob was the likeliest suspect in his wife’s murder, but he had a seemingly airtight alibi: he was at church with their three children at the time of Farah's death. “48 Hours" correspondent Richard Schlesinger reports.
