Darren `Badga' Booth's family have expressed bittersweet relief at the guilty verdict of his killer.
Michael Vernon Lowe, 52, of Waverley, was found guilty of murder in Launceston's Supreme Court today.
The jury deliberated for about 30 minutes this morning before returning the unanimous verdict in front of Justice Robert Pearce.
The verdict followed about five hours of deliberation by the jury on Friday afternoon.
Members of Mr Booth's family, who appeared on each of the 11 days the matter was before the court, began crying at a decision they had been nervously hoping for.
His eldest sister Shirlene Wrigley told the media outside the court that there were no winners only losers in the ``tragedy''.
She said the verdict would not bring her brother back.
Following the verdict the court was read several impact statements written on behalf of Mr Booth's four young children.
Mr Booth, of Kings Meadows, was stabbed to death by Lowe in the early hours of May 13 in Kings Meadows at the home of their joint love interest.
The court heard Lowe was a jilted lover who attacked Mr Booth with a knife when he found him at Crystal Wells home that morning.
In the lead up to the murder Lowe said he ``should knife'' whoever was with Ms Wells, who he'd just separated from, and threatened to find Mr Booth's address and hurt him.
Lowe went to Ms Wells home on the morning in question out of suspicion she was with somebody else, the prosecution said.
When he discovered Mr Booth there ``he lost it'' , pulled a knife and charged the 37-year-old.
The struggle barreled down the home's hallway and finished up in a children's rumpus room.
Mr Booth emerged with three stab wounds to his chest followed by Lowe holding a blood soaked knife.
Lowe apologised and fled the scene.
Mr Booth died in the lounge room from blood loss as a result of the stabbing.
The court heard Ms Wells had suffered ongoing emotional anguish and had never returned to the Pinkard Street home.
