Terry Lubbock, the father of a man found dead in Michael Barry Moore’s swimming pool, has died.
Mr Lubbock, 76, said earlier this year that he had been diagnosed with terminal cancer.
The retired toolmaker, who lived in Harlow, Essex, ran a 20-year campaign for justice for his son.
Stewart Lubbock, 31, died in March 2001 at Barry Moore’s home in Ryden, Essex.
His friend and publisher Harry Seichi said he died Wednesday and paid tribute to him.
“You don’t meet a lot of people like Terry Lubbock,” Mr Seichi said.
“His perseverance and determination was incredible.
Mr Seichi added: “I’ve known him for 16 years. He thought of Stuart every waking hour, seven days a week.
“He died sad, because he knew that people knew he never knew the truth about what happened.
“But no one could have fought for his son more.”
A man was arrested on March 4 in connection with the Stuart Lubbock murder case after new information surfaced following a Channel 4 documentary.
Terry told the PA News Agency at the time: “There’s a lot going on in my head right now. I can’t lift my head around it. Of course I’m happy. Of course this is good news.
“But it’s been 20 years. He’s almost killed me.”
Mr Lubbock also thanked “new witnesses who have come forward”.
An autopsy revealed that Stuart Lubbock had suffered severe internal injuries that showed he had been sexually abused.
Alcohol, ecstasy and cocaine were found in his blood.
A coroner recorded an open decision.
Mr Lubbock, who was divorced and had another son, Kevin, was fighting for a fresh inquiry.
