Yorkshire murder suspect James Allen was 'victim's neighbour' Murder suspect James Allen knew one of his alleged victims, police said today. Cleveland Police said Allen lived next door to Colin Dunford in Middlesbrough. The 35-year-old suspect is being urgently sought by police following the separate murders of Julie Davison, 50, in Whitby, North Yorkshire, and 81-year-old Mr Dunford. At a press conference today Chief Superintendent Gordon Lang confirmed Allen was on court bail for an offence which was not disclosed. He confirmed Allen had also had contact with the probation services and was being investigated for other alleged offences which he would also not disclose. He said Allen had previous convictions for violence and was a known drug user. The detective said there had been a number of reported sightings in Middlesbrough, Scarborough and Whitby. He also urged the suspect to give himself up saying: "James Allen stop now. Do the right thing. Consider the consequences. You have inflicted terrible injuries and death on two families. Stop and hand yourself in. Mr Lang said: "People should take common sense precautions, safety first. Lock their doors, lock their windows and check who's knocking on your door. Clearly this is a man who is a dangerous man but we are putting absolutely everything into finding him, tracking him down and bringing him to justice. There's a massive police operation in place here. Over 100 detectives, two forces, not an inch between these two forces, absolutely working in partnership with one goal and that is to find James Allen and arrest him. I would appeal to general members of the public. If you've got an elderly neighbour then look out for them, reassure them. Be public spirited, be community spirited and help them.
