``WHAT'S it like being a murdering dog?''
That's how Michael Vernon Lowe responded when questioned by the girlfriend of the man he had just stabbed to death, a court has heard.
Mr Lowe, 52, of Waverley, has pleaded not guilty to murdering Kings Meadows man Darren Booth at Kings Meadows last year.
The woman at the centre of the trial gave evidence in the Supreme Court in Launceston yesterday.
Crystal Wells said a fight broke out when Mr Lowe - her former partner of two years - arrived on her doorstep in the early hours of May 13 and found Mr Booth there.
``Lowey reached for the side of his jeans' pocket and pulled the knife,'' she said.
``I yelled out `Lowey's got a knife' and Badger's (Mr Booth's) response was `what knife'.''
Ms Wells fled, called the police and later returned home to find Mr Booth calling for his children.
After Mr Booth was pronounced dead in her living room by paramedics Ms Wells received a call from Mr Lowe, who had left the scene.
``I said, `What's it like being a murdering dog?' '' she said.
``Did he respond?'' Crown prosecutor Linda Mason asked.
``He said, `Good,' '' Ms Wells said.
But defence counsel Greg Richardson suggested Mr Lowe only pulled a knife after Mr Booth had struck him over the head with a wooden implement.
Ms Wells said Mr Booth had not had anything in his hands during the fight.
Another witness, who cannot be named, told the court he saw Mr Booth pick up a blockbuster after Mr Lowe charged him.
``I know Badger swung it, I don't know if it connected with Lowey,'' the teenager said.
The witness said at one stage Mr Lowe was sitting on top of Mr Booth saying, ``I am the law.''
A blood-covered Mr Booth later walked in to the loungeroom followed by Mr Lowe holding a blood stained knife, he said.
``[Mr Lowe said] I think that's enough,'' the witness said.
Under cross-examination the witness said when Mr Lowe arrived at the home he told Ms Wells he wanted to see if she was OK.
The court heard Ms Wells had received a number of abusive messages on May 12 threatening to shoot up her home, which she passed on to her former partner.
In response Mr Lowe sent a message back stating: ``You're no longer my old lady, but no one will hurt you.''
Taxi driver Gregory King picked up Mr Lowe from Kings Meadows McDonald's shortly after the incident.
``[He said] get me the f--- out of here,'' Mr King said.
``He seemed a bit shaken up, nearly out of breath.
``He said he'd just given his ex's boyfriend a flogging.''
Mr Lowe said to keep driving if the police were at the destination, which they weren't, Mr King said.
``He had blood on his hand,'' Mr King said.
``I recognised the smell of blood.''
After dropping off Mr Lowe, who he said wasn't drunk, at Waverley, Mr King saw police heading in that direction.
The trial continues in front of Justice Robert Pearce today.
