A RECONSTRUCTION of the murder of Jim Attfield is being filmed in Colchester by Crimewatch in an attempt to help catch his killers.
Jim Attfield, 33, of East Bay, Colchester, was stabbed 102 times and killed shortly before 6am on Saturday, March 29.
He was found barely alive near Castle Park and Guildford Road and died a short time later.
The killer or killers of the father-of-five have not been caught despite an extensive police investigation.
BBC Crimewatch will be at the scene today and later this week filming a reconstruction to try and help find his killers.
The programme is due to air in June, subject to the ongoing investigation.
A 27-year-old man and woman from Colchester have been rebailed until July 9 after being arrested in connection with the murder.
Detectives are still looking to speak to seven of the more than 20 caught on CCTV in the park that evening who may have crucial information.
Det Chief Insp Simon Werritt said: "We urge them to contact us so we can talk to them and find out what they were doing in the park and then hopefully dismiss them from the enquiry.
"We want to move on and concentrate fully on potential suspects.”
Police are releasing one CCTV image a day to try and focus people's minds.
A Crimestoppers reward of up to £5,000 still remains on offer for information which leads to the arrest and conviction of the person or people responsible for the murder.
Anyone with information is asked to call Essex Police on 101 or Crimestoppers anonymously on 0800 555111.
