Police investigating the murder of James Attfield in Colchester have released three efits of people they want to speak to.
Detectives from the Kent and Essex Serious Crime Directorate are trying to trace these three people, who may have seen something which may assist the investigation.

He suffered 102 stab wounds, and the provisional cause of death was found to be multiple stab wounds.
