A memorial service will be held today to remember a police officer who was shot dead while going to the aid of a member of the public.
Pc Ian Dibell, who was 41, was killed near his home in Clacton when he was off duty on July 9.
It is thought he was going to the aid of Trevor Marshall who was injured in the attack.
His suspected killer, 64-year-old Peter Reeve, shot himself dead in a churchyard in Writtle, near Chelmsford, the following day.
After shooting Pc Dibell, Reeve went on the run, sparking a massive police manhunt.
Hundreds of Pc Dibell's colleagues and members of the public are expected to attend the service at St James Church, Tower Road, Clacton.
A private funeral for Pc Dibell took place last month and was attended by about 130 people.
