How was the Steeltown Murders culprit caught? The BBC are dramatizing the case that went unsolved for so long - until chance evidence emerged.
Landing on BBC One on May 15, Steeltown Murders centres dramatizes the hunt to catch the killer responsible for the murders of three young Port Talbot women in the 1970s. Set in both 1973 and the early 2000s, the case became the first of its kind to be solved nearly 30 years after the killings took place, when a chance encounter allowed pioneering DNA evidence to catch the culprit. Read on to find out exactly Joseph Kappen was linked to the case, allowing the victim's families some closure - although a running theme of the show ponders whether justice can ever truly be found.
