Invisible Monsters: Serial Killers in America

Detectives are at a loss when Ted Bundy, John Wayne Gacy and BTK murder their first victims. Survivors and experts discuss the societal factors that allowed such violent killers to evade police.

Police overlook several tips about Bundy in 1974. He kills four more women by the end of the year. BTK goes dormant - for a time. Gacy hides his crimes behind a thin veneer of public respectability.

Bundy’s brazen attempts to outwit law enforcement have fatal consequences. Dahmer kills his first victim at 18. BTK, seeking notoriety after seven murders, taunts the media. The net closes in on Gacy.

Gacy’s found guilty of 33 murders. Despite murdering multiple women in a matter of weeks, the Green River Killer doesn’t gain the same attention as Bundy, whose trial causes a media frenzy. Why?

Seven years after his last murder, BTK resurfaces to kill his neighbour. Police dismiss a survivor's story about Ridgway. As Dahmer's crimes escalate, law enforcement's actions cause further tragedy.

Public outcry follows Dahmer's arrest. Ridgway confesses to killing up to 80 women after DNA evidence seals his fate. Many fear BTK may never be identified, but Rader's ego brings about his downfall.
