The OAP Killer: First Kill, Last Kill

In the summer of 1986, the elderly population of south London were terrified by reports that a killer was targeting them in their homes. In just 17 weeks, Kenneth Erskine, the Stockwell Strangler, embarked on a spree of sexual assault and murder that shocked Britain. In this film, eminent criminologist Professor David Wilson explores the difference between Erskine's first and last kills in an effort to understand what triggered these crimes and how he was caught.
