ACCUSED Waverley murderer Michael Vernon Lowe went to confront his ex about ``sleeping around'' before stabbing a man in her house to death, police alleged in an interview with the defendant.
The police interview, where Mr Lowe denies the allegation, was shown to the jury yesterday in the Supreme Court in Launceston.
It showed Mr Lowe, who has pleaded not guilty, struggling to account for how Darren Booth ended up with a fatal stab wound following a fight between them.
``I was attacked first, I have had a struggle with him . . . but it was after I was hit in the head when I lose it all, I can't put it together,'' he said.
``I'm trying to piece it together.''
Mr Lowe denied having a knife at the time despite claims from three eye-witnesses that he did.
``How can you explain Badger, I should call him, being stabbed,'' Launceston CIB Detective Senior Sergeant Rick Newman said.
``I can't explain,'' Mr Lowe replied.
He said he couldn't remember telling cab driver Greg King that he probably would have stabbed Mr Booth if the knife hadn't been knocked from his hand.
The 52-year-old said he was out drinking with friends at the Sunnyhill Hotel at Ravenswood before heading to the Commercial in Launceston.
After about 15 drinks he went to the Kings Meadows home of Crystal Wells who he'd been seeing for two years but just recently separated.
Mr Lowe said he got into an argument with Ms Wells after she refused to let him in the house which is when Mr Booth came outside.
``He picked something up and that's when I got hit on the head . . . and after that I can't remember,'' he said.
Detective Senior Constable Russell Forsyth said it was quite a coincidence that his memory faded at this point.
Mr Lowe said he then went to a clubhouse, instead of straight to the hospital, because he wanted to feel safe after being bashed.
Forensic scientist Cory Griffiths analysed the blood splatter in Ms Wells' home for the court.
He said a knife pouch, which police had taken from Mr Lowe's home, contained DNA that was a high grade match to Mr Booth.
Under cross-examination from junior defence counsel Adrian Hall he said a person's DNA could end up on an item even if they never touched it.
Toxicologist Miriam Connor told the court that Mr Booth's body contained alcohol and cannabis at the time of his death but could not say how his behaviour would have been affected.
Mr Lowe will give evidence today in the trial, which is expected to finish next week.
