Officers investigating the murder of a man who was kidnapped from Essex and found with fatal injuries in Hertfordshire are now in a position to name him.

Jack Sullivan, 21, from Waltham Abbey, was taken from the town on 22 June.

During his kidnapping, he was seriously assaulted and sadly died as a result of his injuries.

At this stage three people have been arrested on suspicion of murder. All three have been released on conditional bail as the investigation progresses.

As part of the investigation police are seeking the public’s help in identifying the movements of a black Mitsubishi which was used in the kidnap – and has now been recovered – as well as also locating Jack’s blue Louis Vuitton trainers.

We’re releasing pictures of the vehicle and the trainers today and we’re asking people to please come forward with any information.

DCI Greg Wood, who is leading our 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 3 June, and we are keen to hear from anyone who may have seen this vehicle between 3 June and 23 June, 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.

“We are also asking for help to find Jacks Louis Vuitton blue trainers, which have not been recovered.

“The trainers are worth in the region of £1,000 and believe someone will either be wearing them – perhaps with no knowledge of their prior owner – or attempting to sell them.”

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.”
