Sam Read/The family of a man missing for three months hopes a major aerial and ground search may help to find him.
Thomas Roche, 27, was last seen at 12:30 BST on 6 October when he left the flat he shared with his girlfriend in Chester Close, Bletchley, Buckinghamshire, for a cigarette.
His sister Carly Roche, 35, said three days before he disappeared, he had suffered a head injury after being struck by a car as he cycled down Chepstow Drive, Bletchley.
“Hopefully this search will provide a clue and we may be able to confirm a sighting,” she said.
The charity Civil Air Support said it had been carrying out search flights in the Bletchley area since 2 January, and had captured a number of images for its team to analyse.
On Sunday, about 30 people, accompanied by dogs, gathered to carry out a ground search.
Sam Read / Thames Valley Police, which issued an appeal in October, urged anybody with any information, no matter how significant, to get in touch.
Ms Roche said after the accident, police were called and Mr Reece was taken to hospital “but we believe he did not have a scan on his head”.
She said she feared his head injury may have played a part in his disappearance.,
She said he had been found walking out of a field having not realised he had been gone for so long.
He had propped himself up against a tree, she said, telling family members “One minute it was light and the next minute it was dark,” leading her to guess he was going in and out of consciousness.
His family, including his mother and his twin brother Reece, went out searching for him most days after he disappeared on 6 October, leaving his phone, money and cards.
Ms Roche said it was very out of character for him to go missing.
His children are aged eight, six, five, three and one.
Ms Roche said “no-one has slept properly” and that family members were “constantly on the lookout”.
Family handoutA previous search on Weasel Lane, not far from Mr Reece’s flat, found a empty Monster energy drink can with his DNA on it, but police could not confirm how long it had been there.
Ms Roche said police had flown helicopters and drones over Woburn Woods, and searches had also taken place at Cosgrove, Northamptonshire, where he visited.
She said he could have walked out along Weasel Lane or the A421 without being seen.
