A 37-year-old man has been found guilty of the manslaughter of 18-year-old Jamie Kyne from Claregalway and Jan Wilson, 19, from Scotland.
The judge at Leeds Crown Court this afternoon deferred sentencing on Peter William Brown pending further reports.
Brown was found not guilty of murder and not guilty of arson.
The two apprentice jockeys died in a fire in the block of flats they were staying at in Norton, North Yorkshire, in the early hours of 5 September last year.
Prosecutors claimed at the trial that Peter Brown had lit rubbish in the communal entrance to the block.
Brown, who is from Scotland, had been a former caretaker at the complex, which is home to a number of people working in the local racing industry.
Jamie Kyne's mother Madeleine was in court to hear the unanimous verdict of the jury, made up of six men and six women.
She burst into tears and was assisted from the courtroom by friends and relations when the verdict was read out.
The judge, Mrs Justice Nicola Davies, deferring sentence, paid tribute to the families of Jamie Kyne and Jan Wilson saying: ‘You have attended court every day, my thanks to you for the dignity you have shown.’
In a written statement at the end of the three week trial, the parents of Jamie Kyne said that Peter Brown had robbed them of a fantastic son, leaving the family shattered.
They said their lives would never be the same again.
Madeleine and Gerry Kyne said that they were pleased that Brown had been held accountable for the devastating events of last September but that no punishment would ever bring Jamie back.
They said that Brown had never showed any remorse for what he had done and that he had ruined the lives of all the family including Jamie's younger brothers and his sister.
They said they would now try and re-build their lives without Jamie.
