The mother of a vulnerable man stabbed to death in a frenzied attack in Colchester has appealed for help to catch his killer.
James Attfield was struck down in Castle Park on Saturday.
On Wednesday afternoon police confirmed that one person has been arrested, but stressed that the investigation is still very much active.
At a press conference in Chelmsford earlier in the day, Mr Attfield's mother Julie Finch painted a picture of a quiet, "cowardly" man.
She described him as a loner who loved karaoke and someone who would rather hide away than be in a crowd of people. She also revealed that he was a keen MK Dons supporter.
Holding hands with her husband and daughter for support, she said she'd been left totally numb and appealed to the public for help in finding his killer.
James was found dying in Colchester's Castle Park on Saturday morning - he'd been stabbed 102 times.
The CCTV image below shows him at the River Lodge pub just eight hours before his death.
Today, diving teams and specially trained officers continued searching the waterways for the discarded weapon.
Ms Finch told the press this afternoon that Mr Attfield had been trying to rebuild his life after being hit by a car 4 years ago that left him with a severe brain injury.
Why James was attacked remains a mystery.
His mother hopes that today's appeal will lead to fresh information that may help catch her son's killer.
