Josephine Wentzel was a detective by training and retired when her 30-year-old daughter Crystal was murdered by her new boyfriend. He fled to South America on a forged Canadian passport. He had training in special operations. Even the U.S. Marshals didn't hold out much hope he'd be apprehended. But Josephine had promised she'd take care of her daughter from birth to death - and beyond.

Sheer grit, determination, a careful strategy and time eventually won out. He was captured and returned to the U.S. where he is currently awaiting trial.

Listen as we discuss the self-described "mama bear" bring the wrath of the U.S. government onto the man who stole the life of her daughter and the mother from her tiny grandchildren.
