Police investigating the murder of a 21-year-old man who was kidnapped are trying to find his pair of £1,000 Louis Vuitton trainers.
Jack Sullivan was taken from Waltham Abbey, Essex, on 22 June.
Mr Sullivan was attacked during his kidnap, Essex Police said. He was found "seriously injured" in a car park in Cheshunt, Hertfordshire, the force said. Mr Sullivan was taken to hospital, and died on 26 June.
Police have appealed for help to find Mr Sullivan's blue trainers.
"The trainers are worth in the region of £1,000, and we believe someone will either be wearing them - perhaps with no knowledge of their prior owner - or attempting to sell them," said Detective Chief Inspector Greg Wood on Saturday.
Police have also released a photograph of a black Mitsubishi which was used in the kidnap, and has now been recovered by officers.
DCI Wood, who is leading the investigation, said: "We believe Jack was taken and carried in a black Mitsubishi Outlander that was bearing the registration HY16 FZR - although this is not the vehicle's true registration plate.
"We know the vehicle was stolen from an address in Loughton on June 3, and we are keen to hear from anyone who may have seen this vehicle between June 3 and June 23, when we know it was abandoned in River Close, close to Fishers Close, in Waltham Cross.
"We are equally keen to hear from anyone who may have seen the vehicle abandoned on this day."

DCI Wood added: "At the heart of this investigation is Jack and his loved ones.
"We are determined to provide answers for them, and I would again encourage anyone with information on the Mitsubishi Outlander or the blue Louis Vuitton trainers, to please come forward."
Three people arrested on suspicion of murder have been released on conditional bail, officers said.
