Episode Guide

Jackie Summerford's daughter Bonnie disappeared without trace in 2007. Police found her blood all over the flat of convicted rapist Derek Brown while they were searching for another missing person.

In a landmark case, Brown was convicted of killing both girls in the space of three weeks, despite pleading not guilty and never revealing where he hid the bodies.

With nothing to bury, Jackie now finds herself unable to grieve properly and has no sense of closure over the death of her daughter.

Andrew Jones was the first son of childhood sweethearts Andy and Christine. In 2003, he accidentally bumped into a group of youths while walking home one night, was punched to the ground and died.

No-one has ever been convicted of Andrew's death and the family are furious at the lack of justice. Andy and Christine's relationship has suffered enormously under the weight of grief, as Andy is unable to work and Christine tried to take her own life.

But they still hope that their quest for justice will bring them closer together.

"My father killed my mother..." As a ten year old girl, Diane Yates returned home one evening to find the police surrounding her family home. Her father had stabbed her mother to death in their back garden.

After serving only 18 months in prison, her father was released and the children had to live with him again. Violence has followed them through their own lives and even today, thirty years on, they live under the cloud of knowing that their murderous father can still drop in and visit them whenever he likes.

Alan Kneebone was the perfect son in the perfect family. His friends even teased the young musician about how well the family all got on together. But all this was completely shattered upon Alan being murdered in 2001, devastating the family completely.

His father David turned to alcohol to cope and dropped out of work, while Maureen found it difficult to function. David saw the loss of Alan's life as a sentence worse than any possible criminal conviction. Eight years on, the pain of losing both his son and his best friend still haven't eased.

Sometimes lightning does strike twice. Jean's son Stephen was killed in June 2000 when an obsessed female friend gave him a lethal injection as he was sleeping. Four years later, her grief-stricken daughter Chantel went missing, sparking a nationwide search that only ended 18 months later when police investigating another case found an incriminating letter that led to her killer.

Now Jean is left to pick up the pieces of her broken life, living with the knowledge that both of her children died violently, far too young.

At the turn of 1987 Marcus Van Willing was engaged to be married and had just bought a house with the love of his life, Louise Sutcliffe. This was the happiest Marcus has ever been.

Months later Louise was killed in their new home by a man Marcus had invited back for dinner. More than 20 years later, after spells of alcoholism and homelessness, Marcus is still struggling to come to terms with his grief, guilt and the love he lost.
