The case took five years and Steve and his team through over 3,000 exhibitions up until they lastly discovered the Golden Nugget that brought the killer down.
Cooper was sentenced to life behind bars in 2011 yet his jail time didnt answer all the questions and a dark tale of a possible fifth victim– and 2 more double murders– stays unknown.

Dr Sims, a forensic psychologist, questioned the verdicts reached at the inquest after Coopers conviction in 2011 and stated: “I feel that there would be considerable evidence for looking at this case again as a cold case.”.
He didnt have a criminal record between 1965 and 1983. Cooper was 40 years old at he time of the Scoveston murders in 1985.
