Detectives have appealed to the Facebook friends of a man who was stabbed 102 times, to help solve the mystery of his murder.
James Attfield died after being attacked in Colchester in March. No one has yet been charged in connection with his death.
Essex Police want to speak to anyone who had contact with Mr Attfield on Facebook before he was killed.
They are also putting posters in local pubs to try to identify six men.
A number of CCTV images were released soon after Mr Attfield died, showing people police wanted to speak to.
Det Chief Insp Simon Werrett is hoping the final six men not yet identified will see the new posters and come forward.
He said officers have also been reviewing Mr Attfield’s social media activity as part of the murder investigation.
“If anyone was friends with James on Facebook, and they haven’t yet spoken to police officers, we would ask them to please get in touch,” he asked.
