Meet the woman who wasted 22 years in US jail for a crime she never committed

A woman who spent 22 years on death row in her son's killing tearfully described how she suffered twin tragedies in losing her young child and being the victim of a "blatant miscarriage of justice." Debra Milke spoke out at a news conference on Tuesday, a day after her case was dismissed in the 1989 killing of her 4-year-old son, who thought he was going to see Santa Claus when he was taken to the desert and shot in the back of the head. Her conviction was overturned by an appeals court that ruled her murder conviction was tainted because of the work of a discredited detective.
