Secret listening devices placed at the home of the "prime suspect" for the murder of an auto wrecker recorded nothing about the killing, a jury has been told.
While Kubilay Kilincer was involved in lots of discussions about money, there was nothing about the killing of his boss, a retired police officer testified on Friday.
The 60-year-old has pleaded not guilty to murdering Hasan Dastan, the owner of Esy Auto Dismantlers in Blacktown, on the morning of Monday December 11, 1995.
Mr Dastan was found dead in a pool of blood lying partially under a car.
A metal pipe was shoved six centimetres into his mouth and his severe head injuries were consistent with an attack using a bloodied sledgehammer that lay nearby.
Kilincer, Mr Dastan's only employee, told police his boss was fine when he left the premises at about 8.50am for a few hours before returning to be told he had been killed.
Retired chief inspector Stephen Dale told the Supreme Court jury he was in charge of the case in 1995 and 1996,
Mr Dastan's wife said she believed her husband had $6000 on him when he left for work, money which was not located at the scene.
She also told police her husband had never spoken to her about sacking Kilincer.
Asked by Kilincer's barrister Ertunc Ozen SC if there were a number of suspects or persons-of-interest, Mr Dale replied: "I would say no".
While there had been conflict between Mr Dastan and his son, and also issues about a number of car part business transactions, he said he would not call them suspects.
He agreed Kilincer's home was subject to a listening device while the son's home was not and neither was the home of a woman who had made threats against Mr Dastan.
Kilincer was also placed under surveillance.
"Police were directing their resources at the person who they considered the prime suspect," Mr Ozen asked.
"I agree with that," Mr Dale replied.
He agreed Kilincer spoke to police at the death scene, voluntarily made statements and a record of interview, and allowed police access to his home.
The listening devices revealed discussions about money but nothing about the killing.
He agreed with Mr Ozen that he didn't hear Kilincer say anything about killing anybody, or about throwing away clothes, or about creating a false alibi.
The trial, before Justice Helen Wilson, will resume on Tuesday.
