This is the first picture of killer Shaun Wainwright – who bludgeoned his workmate Simon Holdsworth to death in a revenge attack.
The jury reached a unanimous verdict in under two hours.
Simon’s family were in tears at Teesside Crown court as the verdict was read out.
The judge told Wainwright he will be jailed for life but will rule on the minimum term he must serve tomorrow.
In a statement released by Simon Holdsworth’s family today, they said: “Simon was a much loved son, brother, fiancée, father and uncle.
“Our family have been totally devastated by what has happened to Simon. His life was brutally ended in the most horrific circumstances. Our lives will never be the same again.
“We miss Simon everyday. He will be forever in our hearts.
“We would like to thank the prosecution team and South Yorkshire Police, particularly DCI Etheridge and his team, for their outstanding and professional way in which they have conducted this investigation and brought Shaun Wainwright to justice.”
Teesside Crown Court heard Wainwright lay in wait for Mr Holdsworth and attacked him as he walked across playing fields to his home.
The jury was told the Sheffield factory worker killed colleague Simon Holdsworth in ‘revenge’ after an argument about a forgotten wallet.
Prosecutor Peter Moulson QC said Shaun Wainwright was angry with Mr Holdsworth for refusing to reopen the factory where they both worked and he had left his wallet after a night shift.
Wainwright, aged 46, of Dagnam Road, Arbourthorne, told police he got on well with 36-year-old Mr Holdsworth and could not understand why he had been killed.
But the prosecution said he lay in wait in the dark and attacked him with a blunt weapon on playing field by Rainbow Forge Primary School in Hackenthorpe on December 16, 2013.
Wainwright and Mr Holdsworth worked together at FBS Prestige on Birley Vale Avenue.
Detective Chief Inspector Phil Etheridge, the Senior Investigating Officer, said today: “We know that Shaun Wainwright has a history of holding grudges against people for relatively minor things.
“He’s had workplace disputes before where he has physically assaulted people. We believe Wainwright was angry that Simon would not allow him to get his wallet back. Something so simple, we believe, cost Simon his life.”
In the weeks after Simon’s death, police also discovered that Wainwright had discussed details with others that only the killer could have known.
DCI Etheridge said: “On Christmas Eve, we know that Wainwright told a friend that Simon had been robbed and that his phone and chain had been stolen. This information was not made public until 3 January 2014 – clear evidence that he knew much more than he was admitting to.”
A post mortem found that Simon had been hit with a blunt instrument, which caused fatal head injuries. The murder weapon has never been found, although police believe a metal bar taken by Wainwright from his workplace, which he had told colleagues was for ‘protection,’ was used to attack his victim.
DCI Etheridge added: “Wainwright is a man who claimed to be Simon’s friend at work and has lied constantly and repeatedly throughout the investigation. He’s physically much bigger than the victim and overpowered him, leaving him for dead – all of this points to the actions of a violent bully.
“He knew where Simon would be that night and he drove to the scene intent on revenge for a dispute he had with him. The defendant has a short fuse and responded with maximum force over a minor grievance.
“Simon’s family have lost someone they loved dearly and Shaun Wainwright’s family have lost someone too – there are no winners here.”
