The son of small-town police officer Drew Peterson, Stephen Peterson, must face up to the terrible truth when his father becomes a media sensation after being accused of murdering his third wife and suspected in the disappearance of his fourth. When a killer strikes, most of us think first of the victim – of their struggle, of their violent death. But murderers do more than just kill their targets– they irreparably harm their own family – often leaving them physically battered, emotionally scarred, financially ruined and ostracized by neighbours and friends. A killer’s kin – his wife, sons or daughters – are the unrecognized victims of his violent crimes. 'I Lived With a Killer' tells their compelling stories.
