Lisa Dorrian 2005 murder: £20,000 reward for body recovery information or conviction

The appeal is backed by a reward from the charity Crimestoppers.

Crimestoppers have put up a reward of up to £20,000 for information leading to either the arrest and conviction of those responsible for the murder of Lisa, or for information that results in the recovery of her body.

Lisa, from Bangor, was just 25 years old when she was murdered.

She was last seen alive on the night of Sunday February 27, 2005 at a party in Ballyhalbert Caravan Park. It’s believed she was murdered that night or in the early hours of the following morning.

Detective Superintendent Eamonn Corrigan said: “Despite extensive search operations and thousands of lines of enquiries 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.

“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.”

Speaking about the reward, he added: “I’m keen to highlight a reward of up to £20,000 from Crimestoppers, who are a charity and are independent of the police. It’s especially noteworthy, and indeed unusual, that this reward is being offered for either information given directly to Crimestoppers that leads to the arrest and conviction of those responsible for Lisa’s murder, or for information that results in the recovery of her body. And, of course, this information can be given anonymously, meaning Crimestoppers will never ask for or store any of your personal details.

“Contact Crimestoppers on freephone 0800 555 111 or online at www.crimestoppers-uk.org. There is no caller line display, no 1471 facility and computer IP addresses are never traced or provided to detectives.

“It is not too late to do the right thing and to help bring some form of closure to years of torment.”

"I am asking you to imagine, just for one minute, how Lisa’s family and friends must feel every waking day. Please search your conscience and come forward.”
