The man who died after being shot through the chest with a crossbow had just hours earlier been celebrating winning a stock car race.
A friend of Darrell Farnham told the Bucks Herald how he had been ‘chuffed’ at winning a trophy.
People have been leaving tributes on the 44 year old’s recovery truck near his Belgrave Road home.
Mr Farnham, who spent his time recovering and fixing vehicles for a living, was found ‘beyond help’ at his home at around 10.45pm on Sunday and died at the scene.
One of his friends, who did not want to be named, said: “He went racing that day and won first place.
“He was so happy and showing me the trophy.
“I knew him since I was a kid.
“I could go round there for a cup of tea and he would say ‘come in son’.
“If you broke down anywhere he would come and recover you.
“It really brought me down what happened.
“It’s not right, that sort of thing shouldn’t happen.”
Flowers, balloons and messages of condolence have been left near the spot where Mr Farnham died.
One message said: “I will never forget you. You were like a brother to me.”
Another read: “Can’t believe your gone. Thank you for everything you done for me and my family. Will never forget you. Love you Daz.”
Part of Belgrave Road near Mr Farnham’s home remains cordoned off by police.
Nearby residents have expressed their shock at the ‘terrible’ incident.
Mark Kelly, one of Mr Farnham’s neighbours, said: “He was always nice to us and polite and pleasant to the kids.
“We were quite upset when we found out what happened.”
On Thursday afternoon two more people were arrested in connection with his death.
A 42-year-old man was arrested on suspicion of murder and a 36-year-old woman was arrested on suspicion of assisting an offender. They are both currently in police custody.
Two people arrested earlier in the week, a 40-year-old man from Aylesbury who was arrested on suspicion of murder and a 37-year-old woman who was arrested on suspicion of assisting an offender, are due to answer bail today.
Police are continuing to appeal for anyone with information about the incident to come forward.
Anyone with information should call police on 101 or Crimestoppers anonymously on 0800 555 111.
