Detective Superintendent Eamonn Corrigan said: “Despite extensive search operations and thousands of lines of inquiries being completed, Lisa’s body has not been found, and those responsible for her murder have not been brought to justice.
“It’s almost 18 years on, and the pain still felt by Lisa’s family is understandably as raw as ever.
“Lisa’s family and friends won’t ever give up their search for answers and, likewise, our determination remains steadfast.”
Mr Corrigan added: “Those responsible, and those withholding information, must surely have a heavy conscience? They are denying this family the most basic of rights, and that’s the right to lay their loved one to rest.”
