“We will also visit mum’s grave where Lisa’s name was added last year and lay flowers in the hope that one day we will be able to give Lisa the Christian burial she deserves.
“Since Lisa was murdered we have had family celebrations, birthdays, births and deaths and have felt the loss of Lisa at every single one.
“Twenty years ago, we lost our beautiful sister and daughter but, even more importantly, Lisa lost her life at the hands of people she knew and trusted,” they said.
Ms Dorrian’s father John and sisters Joanne and Michelle stood alongside PSNI Detective Chief Inspector Kerrie Foreman at police headquarters on Thursday morning in the latest of scores of appeals to find her over the last two decades.
The family of Lisa Dorrian have described enduring a “lifetime of pain” on the 20th anniversary of her disappearance and murder.
