IT TOOK less than 25 minutes for a jury to decide that Craig Andrew Holzberger murdered his girlfriend and destroyed the life of her unborn child.
After a six-day trial in Bundaberg Supreme Court, the jury was this afternoon quick to rule that on March 21, 2011 Holzberger meant to kill or cause grievous bodily harm to 24-year-old Tenille Hass, his girlfriend of nine years, when he stabbed her three times - twice to the chest and once to the shoulder.
At the time of her violent death, Tenille was pregnant with the child of Holzberger's friend Christopher Green, with whom she had a relationship while Hozberger was serving time in prison.
In his closing address, crown prosecutor Greg Cummings said Tenille, Green and Holzberger had all been using prescription drugs and drinking alcohol on the night of the murder.
Holzberger had admitted to the manslaughter of Tenille and to causing the death of her baby.
But for him to be convicted of murder Mr Cummings had to prove Hozlberger had intent to either kill or cause grievous bodily harm.
"If you pick up a knife you do so for a particular reason," Mr Cummings said of Holzberger's intent.
"He says he's never carried a knife so when he went to the sink and selected that knife. What was the reason if not to attack Tenille with it?"
Tenille was stabbed with a large kitchen knife measuring 188mm from tip to hilt.
"Not one of those penetrations from the knife blade was less than 70mm," Mr Cummings said.
"These were not timid, tentative blows.
"He armed himself with a completely unforgiving weapon."
Mr Cummings said Tenille was not armed and had no time to defend herself.
"He selected an area where human beings are particularly vulnerable to attack," he said.
"(There was) serious violence was inflicted on this lady."
Holzberger, 39, did not react as the jury delivered its verdict shortly before 5pm, blinking rapidly and staring straight ahead.
Holzberger is expected to be sentenced tomorrow on charges of murder and destroying the life of an unborn child.
