Serial Killer on Video

Closed-circuit television footage that led British police to identify Stephen Griffiths as a serial killer shows the self-proclaimed "Crossbow Cannibal" carrying a crossbow in the hallway outside his apartment shortly after he killed one of his victims, then raising his middle finger to the camera.

The video was recorded minutes after he killed Suzanne Blamires, one of three prostitutes Griffiths confessed to killing, police said. Griffiths was sentenced to life in prison after pleading guilty this month to the murders of Blamires, 36; Susan Rushworth, 43; and Shelley Armitage, 31.
