New techniques in DNA testing are to be used by police in a bid to find the mother of a baby found dead on waste ground in Edinburgh's Craigmillar area.
Hundreds of mourners attended Craig Millar's funeral
The case, which shocked Edinburgh residents in 2001 will be the first project re-examined by Lothian Borders newly-formed Serious Crime Review Unit.
The child's body was found dumped on a footpath on Sunday 11 March 2001 just after 0800 BST by a dog walker.
The baby boy was later given the name Craig Millar by local residents.
At the time more than 30 officers tried to establish who the parents were, how the child had died and why he was abandoned in such bleak conditions.
Despite extensive inquiries and massive media attention no-one ever came forward to claim the child and the parents remain unidentified.
Police set up a confidential phone-line during the investigation, spoke to about 1,000 people, took 300 statements and delivered 1,000 letters to the local community appealing for information.
Craig Millar was wearing a Mickey Mouse outfit
Bert Swanson, a retired Detective Superintendent from Lothian and Borders Police with 33 years police service, is the unit's review manager.
He said: "This is the first case that the new unit has taken on but will be reviewing a wide range of serious unsolved crimes.
"With this particular case we hope that advances in DNA technology over the past five years might give us a new opportunity to trace the biological parents.
"Perhaps as time has passed people who did not come forward when baby Craig Millar was discovered may be more inclined to do so now.
"We have some clues which may help jog people's memory what the baby was wearing and what he was wrapped in.
"We would also like to hear from anyone who remembers a woman pregnant in the early part of that year who did not go on to have a baby."
