Britain's Most Evil Killers - John Cooper

Tune in tonight to Sky Crime at 9pm to find out from Professor Angela Gallop and Dr Philip Avenell how up to twenty years later, detailed investigation of clothing and other items uncovered a complex web of textile fibres which provided powerful links between the suspect, John Cooper, and victims of the Pembrokeshire Coastal Path and other murders and crimes. Combined with DNA evidence revealed by meticulous searching, this contributed to Cooper’s conviction in 2011. The scientists involved all received formal commendations for their work.
