Suicide threat may have come before fatal stabbing

ZARKO ILIC was allegedly seen in his kitchen wielding two knives and threatening to kill himself moments before his step-father was found with a blade protruding from his lifeless body.

But Ilic's defence barrister, Dennis Lynch, has told the jury in the murder trial, Ilic did not kill Ivan Martic.

Ilic, who is on trial in Brisbane Supreme Court, has pleaded not guilty to killing his step-father in their Goodna home in September, 2009.

During the first day of his trial on Wednesday, the jury heard Ilic and Mr Martic had long-running animosity.

Crown prosecutor Brendan Campbell said Mr Martic had called Ilic a "leech" and a "parasite".

Mr Martic further complained Ilic was a 27-year-old who still lived at home with no house of his own and no girlfriend.

Ilic's grandmother, mother - Mr Martic's wife - and half-brothers were also living in the Goodna home in 2009.

The jury heard Mr Martic, a heavy drinker, called his wife in June or July, 2009, and threatened to kill her mother.

Mr Campbell said Mr Martic later pulled his wife's mother by the legs.

The court heard Ilic found out about the confrontation between his grandmother and Mr Martic, which happened when he was away.

On the day Mr Martic died, he called his wife and complained Ilic had parked in his car park.

Mr Campbell told the court while that may seem "childish" it was background to what happened later that day.

Later that night, Mr Martic, who was drinking, allegedly threatened to punch Ilic.

Mr Campbell said family members saw Ilic grab two knives and wave them around saying he was going to kill himself.

Mr Campbell told the jury they would hear from police evidence that Mr Martic was found with the blade of a knife embedded in his back and a pool of blood beneath him.

The court heard when police arrested Ilic after a car chase, Ilic said "shoot me, just shoot me".

Mr Lynch told the jury it could not be proved Ilic caused the death and no one saw him inflict the stab wounds.

Mr Lynch said Mr Martic threatened to kill himself after drinking alcohol in the past and submitted Mr Martic's hair and blood was found on a knife hole in the wall.

"If you put together all of these things, there is evidence to suggest Ivan Martic had possession of the knife while it was still intact and after he was bleeding and clearly before he was fatally stabbed," he said.

The trial continues.
