Behind Closed Doors (2003)

The unthinkable happens with alarming frequency: a family is destroyed by its own member nearly every two months. The story of the Mochrie family in Barrie, South Wales, stands out as one of the most shocking instances of this tragedy. To those who knew them, the Mochries were a typical, happy middle-class family. But one summer night, their ordinary life was irrevocably shattered. Robert Mochrie, a loving father and husband, murdered his four children and his wife before taking his own life. The film explores the devastating question: why do these mass family murders occur, and why are they becoming increasingly common?
