MURDERED: Jodine Serrin Part 1
On Valentine’s Day in 2007, 39-year-old Jodine Serrin was brutally murdered and desecrated in her own bed – while her parents were just down the hall. Over the next 10 years, using new forensic techniques, the Carlsbad Police Department identified her killer. But when they did, everyone was forced to confront the chilling realization that this man had been leading a double life – on one hand, living like you and I, acting as a father, partner and employee. On the other, he was a monster.
