Detectives investigating the death of an A-level student at a party in Colchester have said they believe people who know the identity of his killer are yet to come forward.
Jay Whiston was stabbed at a house party attended by about 100 teenagers on Marlowe Way shortly after 10pm on September 8th.
The 17-year-old, from Clacton, died in hospital and a post-mortem showed he died from a stab wound.
It is believed details of the party were circulated on Facebook and a number of uninvited guests turned up.
Partygoers were interviewed by officers in the days following the murder, but detectives are yet to find his killer or the knife used in the attack.
Detective Chief Inspector Simon Parkes said: "We're extremely grateful for the help we've had from the teenagers so far.
"Jay's parents, Caroline and Shearer, lost their son. Although they have been hugely impressed by those who have come forward so far, they together with other family members and friends need some closure. We believe there are still people who know who is responsible for Jay's stabbing."
A number of knives were recovered from the area surrounding the house but police do not believe any of them were the murder weapon.
Five people from Colchester were arrested on suspicion of murder during the hours and days following the stabbing. The three 18-year-old men and two 17-year-old boys have had their police bail extended until November 22nd.
Anyone with information in connection with this death is urged to contact detectives at Colchester's major investigation team on 101.
