The family of a County Durham man, who was murdered nearly 25 years ago, have offered a £50,000 reward to anyone who comes forward with new information which helps secure a conviction.
The body of Paul Logan from Blackhill, Consett, was found on farmland near Shotley Bridge in the early hours of Christmas Eve, 1993.
He was a delivery driver for the Golden Flower Chinese restaurant and had been lured to Blue House Farm, Shotley Bridge, by his killers on the pretext of delivering a Chinese meal.
Watch Kris Jepson's report here:
This followed a hoax call made from a telephone kiosk at the junction of Snows Green Road and Benfieldside Road, Shotley Bridge.
At the time the call was made, a man was seen in the kiosk while another waited outside in a red Ford Fiesta.
When he arrived at the farmhouse, just before 10pm on December 23, Paul was told by the householders that no meal had been ordered.
He left the house but the householders' suspicions were aroused later that evening when they noticed that Paul's cream Peugeot car was still at the end of the lane leading up to their home.
Police found the car empty with the lights still on and the doors open.
Officers searched the area, finding his body about 50 yards away at around 2.15am.
He had suffered severe head injuries caused by a blunt instrument which has never been recovered.
Anyone with any information has been asked to call Northumbria Police on 101, or Crimestoppers anonymously on 0800 555 111.
