When Christine Collins’ nine year old son Walter went missing in 1928, she insisted the LAPD find him. When they introduced her to a boy who claimed he was Walter, Christine knew he wasn’t her son. Considering her too much trouble, the LAPD committed her to the Psychopathic Ward of the Los Angeles County Hospital. But there was even more to Walter’s disappearance than just a boy gone missing and another acting as an imposter. Christine’s story would soon be found to be connected to a serial killing mother-son team and one of the most devastating murder cases in California history.
