DARREN Booth's murder was a crime of passion committed by a man who could not accept that the woman he loved felt differently.
About a month before the murder, Lowe and long-term partner Crystal Wells, 20 years his junior, began what was described as a trial separation.
But Lowe refused to believe things were over and questioned her friends about who Ms Wells was seeing and even had her father talk to her about getting back with him.
A few weeks before the incident Lowe had met Mr Booth in her home, later texting Ms Wells "he'll be hurt".
Around the same time he told a witness he "should knife" whoever was with Ms Wells, but changed his mind because it would "wreck [his] chances with Crystal".
In the hours before the murder Lowe was drinking at the Sunny Hill Country Club and the Commercial Hotel, when he discovered two things.
The first was an indiscretion early on in their relationship and secondly Ms Wells was not out that night with a friend as she had claimed.
Carrying a knife, as he always did, he decided to confront Ms Wells at her home.
When he discovered Mr Booth at the Kings Meadows home it was a "light bulb" moment, prosecutor Linda Mason said.
"He saw red and he attacked," she said.
Lowe charged at Mr Booth with a knife, eventually stabbing and killing him.
He then fled the scene, first going home and then to a clubhouse.
Lowe either cleaned or had someone else clean his knife and the shirt he was wearing when he murdered Mr Booth.
Ms Wells had been receiving threatening text messages about her house being blown up on the day before the murder.
She forwarded these to Lowe, seeking his protection.
After drinking at the Sunny Hill Country Club, he became worried about Ms Wells and decided to check in on her at 1.30am.
As Lowe was talking to Ms Wells, Mr Booth came to the door and attacked him with a cricket stump.
The warehouse storeman, who wore a knife for cutting boxes at work, pulled it out, this time to defend himself from Mr Booth.
Lowe stabbed Mr Booth but only in self- defence and was suffering concussion when he left the scene and was unable to recall many details to police.
Police recovered Lowe's clean hunting knife in its pouch in a filing cabinet at his Waverley home.
Traces of blood were detected on the pouch, which contained a high-grade match to Mr Booth's DNA.
Both sides said a blood spatter analysis showing mainly Lowe's blood in the front of the home supported their version of events.
Ms Mason said it showed Lowe, after being hit over the head, continued pursuing Mr Booth through the home until he killed him.
Defence counsel Greg Richardson said it showed his client was the victim.
Few Launceston trials are as graphic as this one. Members of the Booth family were unprepared for the video examination of the murder scene which showed Mr Booth's body lying in- situ in the middle of Ms Wells's lounge room, where he was pronounced dead. The forensic video showed close-ups of Mr Booth, including his stab wounds, shocking the Booth family. Most cried openly in the court, but Mr Booth's brother, unable to contain his emotions, began swearing at Lowe, who was sitting two metres away in the dock.
What Lowe did after the murder that implied guilt and how the defence responded:
Lowe lied to police when he said he didn't have a knife during the fight. The defence said Lowe had memory loss resulting from concussion.
Lowe fled the scene, implying a guilty conscience. The defence said: "He didn't go to Brazil, he went to hospital."
The shirt he was wearing during the fight and the knife were quickly washed. The defence said there was no evidence that he washed it.
Following the murder, he went to a clubhouse at Invermay. The defence said he wanted to go somewhere safe because of fear of possible retribution from Mr Booth, who he didn't know had died.
He told a cab driver to keep driving if the police were at his home just after the stabbing.
Sent a text to Ms Wells warning her not to tell the police. The defence said he was worried Ms Wells would construct a version of events framing him.
Did not hand himself in after a Launceston detective told him to do so shortly after the murder. The defence said it was his son, not Mr Lowe, who spoke to the officer.
