Colchester Castle Park death victim was 'shy and polite'
A man who died after being found with severe injuries in an Essex park has been described as a "shy and polite son, brother and father" by his family.
James Attfield, 33, of East Bay, Colchester, had injuries to his head, upper body and hands when he was found in Castle Park early on Saturday.
He died at the scene and police are treating his death as murder.
Mr Attfield suffered a brain injury in a car accident four years ago, leaving one side of his body weak.
His reasoning and speech had also been affected.
His mother Julie Finch said her son was "vulnerable" and did not like going to crowded places because he knew he had to keep away from trouble that might lead to further injury.
"Jim was never the type of person to look for a fight and would always back down or walk away," she said.
"Even after his accident he was always smiling and continuously challenging himself.
"He wanted to be the best he could be.
"Jim was loved by his family and will be missed."
Police believe a bladed weapon was used in the attack.
They want to hear from anyone who may have seen Mr Attfield in Colchester town centre or Castle Park so they can piece together his movements on Friday evening and Saturday morning.
Officers are also looking for information about a man seen waking along East Hill at 05:30 GMT on Saturday.
