Missing RAF Serviceman: Drive to hire private investigator passes £20k target
A crowdfunding campaign to hire a private investigator to search for a missing RAF serviceman has exceeded its £20,000 target in less than two days.
Corrie McKeague, 23, was last seen in the early hours of September 24 in Bury St Edmunds, Suffolk.
He was reported missing when he failed to turn up at his base, RAF Honington, 10 miles (16km) from the town.
His mother, Nicola Urquhart, of Dunfermline, said on Tuesday that she had "no faith'' the police would find him.
She voiced concerns over the resources of Suffolk Police.
A JustGiving page was set up later that day by Cheryl Hickman, who runs the Suffolk hotel where Mrs Urquhart has been staying since her son went missing.
Temporary Assistant Chief Constable Louisa Pepper said she had "absolute confidence'' in her team and that similar resources were being put into the search as would be put into a murder investigation.
The fundraising page said donations would be used to fund the appointment of a private investigator and a data analyst to go through the information gathered.
Mr McKeague's grandparents had earlier pledged a "five-figure reward'' for information leading to his safe return.
Another girl was airlifted to hospital.
The attack happened on Waverley Bridge.
Opposition parties are criticising the figures.
