A mourning mother has fresh hopes that the net will finally close around the hit and run driver who killed her son in 2008.
To mark the four-year anniversary tomorrow (Friday) police have decided to take a new look at the case, starting with 150 hours of CCTV footage from Corporation Road, where dad-of-two Paul Davis was struck.
His mother Pauline Davis said: “They told me it was the only unsolved road fatality in Derbyshire and that they are pulling out all the stops.
“Money is no problem. They are putting photographs in local pubs and are going to interview all the witnesses again, rather than going through the statements they first made.
“It will be a new team starting from the beginning and that is really good. They don’t just want to look at what they have already got.”
Machinist Mr Davis, 37, lived on Corporation Road with his partner Joanne and was struck as he walked home after a night out in Ilkeston.
Police launched a major enquiry – including examining 400 silver Ford Mondeos – after a sighting.
A witness spoke of a vehicle going up the road and turning back, as if he realised he had struck someone and wanted to assess what had happened.
Nobody ever came forward to admit being the driver and police were unable to charge anybody with the offence following the crash at about 2.10am on August 10, 2008.
Mr Davis’ son Aidan, 19, said: “We just want to find out who did it. I think of my dad every day. He used to take me on holiday and fishing, all sorts like that.”
Mrs Davis of Heanor Road, Ilkeston said: “At 15, it’s a terrible age to lose a parent and it is awful for Aidan.
“We want justice for Paul. We want somebody to be caught and taken to court.”
Her partner of 15 years, Keith Foster, 50, said: “People talk and somebody may remember something that was said.”
Police have told the family about advances in film equipment, which could be crucial in identifying vehicles.
On the door, one vehicle had a business sign, like those used by cabs and private hire firms.
The film also shows lights in the middle of the dashboard which could have been a taxi meter, sat nav or mobile phone.
Chf Insp Steve Wilson, head of roads policing, said: “We want to appeal to anyone who has any information about the incident, even if you felt it was insignificant at the time.
“Someone you know may have been acting unusual around the time of Mr Davis’ death and may display similar behaviour after this appeal.
“Your circumstances may have changed in the last four years, you may now be in a position to come forward. Any information you have could be vital.”
“Mr Davis was a hard-working family man and what happened to him was a tragedy and a terrible loss for his family and friends,” said Chf Insp Wilson.
“Someone out there knows what happened and I would appeal to you to come forward and help us find some answers for the family.”
Anyone with information should call police on 101 or Crimestoppers anonymously on 0800 555 111.
