Case 1: Jean and Tony Simester's son Darrell went missing in the year 2000. Fearing he was being held against his will, they contacted the police but, because of Darrell's age, were unable to find the help they so desperately needed. It was only after an observant member of the public, who'd read a newspaper article about Darrell, that they got the tip-off they needed. Having spent 13 years as a slave, Darrell was ill – both physically and mentally.Case 2: In 2012 Shelley Roylance's husband tragically lost his life to cancer. In her grief Shelley turned to her family for support. Her eldest son Paul agreed to manage the £45,000 estate left to her by their father. The decision would have tragic consequences.
