The victim from Wednesday afternoon's stabbing at Stourbridge Common in Cambridge has been named as 46 year-old Peter Anderson of Heath House.
Police have now made a fresh appeal for people to come forward following Mr Anderson's death.
Emergency services were called to Stourbridge Common at around 415pm on Wednesday. Detectives say they know there were many people on, or crossing, the common at the time of the attack who have not yet spoken to them.
Today, a statement from Mr Anderson's partner reads:
"Peter, aka Blue, was loved by many and will be greatly missed.
I and Peter's other loved ones would now like time to grieve in private."
A post mortem examination carried out yesterday at Peterborough City Hospital concluded Mr Anderson died of stab wounds.
A 17 year-old boy who was arrested on suspicion of murder has been released with no further action taken.
A police cordon remains in place at the scene today as a police team continues to carry out searches.
DCI Mike Branston, who is leading a team of detectives dedicated to the murder, said:
"I am appealing directly to those people who were at the scene on Wednesday afternoon to get in touch because the information they provide could be the key to this investigation.
A man has been brutally murdered and we are committed to bringing whoever attacked him to justice.
There were some young people on the common that afternoon and cyclists passing by and I would ask anyone who was in that area, between 3.30pm and 5pm on Wednesday, to come forward and help us get justice for Peter and his loved ones.
We are treating this attack as an isolated incident, however, there will be a police presence in the area over the weekend."
