The Grinning Killer Chris Halliwell - How Many Women Do You Have to Kill to Be a Serial Killer?

Superintendent Steve Fulcher had not followed procedure. Due to this monumental error in judgement infamous killer Christopher Halliwell could not be convicted of a second murder, despite him openly admitting to having done so. Fulcher was suspended for gross misconduct, and later quit the force. Halliwell, imprisoned for the first murder, was later convicted of the second, after a long and tortuous process of collecting new evidence. But the police, including Fulcher, remain convinced that he has killed other women known to have disappeared.
