The search for a postman who went missing from St Neots earlier this month has entered its third week.
Darren Willis, 53, was reported missing from his home on Duck Lane on June 9.
Taking to social media today (Monday June 30), his wife Sarah explained "everyday gets harder", adding that "no one knows the love our family has for you."
It comes after Cambridgeshire Police released a CCTV image of the last known sighting of the postie on June 25, as they say they "haven't given up hope of finding him alive".
A number of unconfirmed sightings have been reported in recent weeks, with a number of searches covering St Neots.
Supported by Cambridgeshire Search and Rescue and Midshires Search and Rescue, the searches have focussed on green spaces and areas of open water.
There have also been two unconfirmed sightings in the Willington area of Bedfordshire and officers are speaking with locals and checking CCTV.
The last known sighting of Darren was from just before 7am on June 9, on a pathway connecting Willow Bridge and Shakespeare Road in St Neots.
On June 12, members of the public assembled at Coneygeare Car Park to search for Mr Willis.
It was later announced that the search for the missing postman had extended to another county.
The search for the 53-year-old widened to Bedfordshire, according to officers searching for the father-of-three.
However, the force is now pursuing a line of enquiry suggesting Darren could still be in the community and in need of help and support.
DI Emma Garwood, who is leading the searches, said: "Previous appeals have generated information from the public and we’re very grateful for the support we’ve received so far."
"We grow more concerned the longer Darren is missing but we haven’t given up hope of finding him alive.
"If anyone thinks they may have seen Darren from the CCTV image we’ve released, which we believe to be him, please get in touch.", DI Garwood said.
Mr Willis is described as 6’2”, medium build and is believed to be wearing dark navy jeans and a navy hoodie. He may also be wearing a baseball cap.
Anyone who has information concerning Mr Willis' whereabouts should call 101 quoting incident 83 of June 9.
