It was six years ago when Lucy, would have celebrated her 28th birthday this year, was shot dead at her home in Walton.
In the early hours of 3 August 2005, three men burst into her home on Lambourne Road, Walton, they shot Lucy, as she lay on the sofa downstairs. Lucy's partner Gary and their two-year old daughter were sleep upstairs.
Even as a toddler was heard crying upstairs, the offenders poured petrol around the living room and set fire to the house.
Detectives believe the offenders would have been in no doubt they were killing a young woman, with police saying they could have claimed the lives of two more people that night had Gary not escaped the flames by jumping, with his daughter in his arms, from an upstairs window.
Detective Superintendent Ian Mulcahey said: "Six years on and we are determined as ever to find justice for Lucy and her family.
"Lucy was an innocent victim and her death has not only robbed her three children of a mother, but also her parents of a loving daughter.
"We believe that someone, somewhere knows what has happened to Lucy and I hope that the passing of time will enable people to search their consciences and find the courage to come forward.
"It's never too late, any information we are given will be acted upon."
