IIRC during the Zahra Baker investigation it was thought her father was driving all over two counties disposing of her dismembered body when it was actually her step-mother, Lisa, who had his cell phone. He was at work and it was verified during those times. Whether this was intentional on Lisa's part, I don't know. So this former TBI should have some common sense to know phones are capable of being away from their owners. Basing an investigation soley on cell phone pings really isn't good investigation, in my opinion. Someone should teach him how to do old school investigation like Cagney & Lacey.
