Sean Christian Price has been sentenced to life behind bars for the murder of Doncaster schoolgirl Masa Vukotic.
Price was handed his sentence in the Supreme Court this morning, almost a year to the day after he killed the 17-year-old by stabbing her almost 50 times in a park.
He will be eligible for parole in 2054.
Justice Lex Lasry said it was a "catastrophic example of mismanagement" that Price was allowed back into the community.
Price was on bail when he brutally murdered Ms Vukotic.
EARLIER: Almost one year to the day after 17-year-old schoolgirl Masa Vukotic was murdered, her killer Sean Price will be sentenced for his heinous crime in the Victorian Supreme Court.
Judge Lex Lasry will announce the sentence in court 4 at 10.30am on Friday.
The state government has said it will release the Harper review into problems in the Victorian corrections system after Price is sentenced.
Price was about to set off on his mission to kill on March 17, 2015, placing a large kitchen knife inside his sock.
But just as he was walking out of the door of his Albion apartment, he realised the knife could be easily seen so he hid it in a black bag and placed a number of CDs over the top of it.
Price, 32, also put a T-shirt in the bag anticipating he would end up covered in blood and would need to change his shirt.
He claimed to have had little sleep in the weeks leading up to the murder, and had been using cannabis and alcohol to try to help him relax because he felt "wound up".
He later told police he had wanted to stab someone because "I just hated society".
"I just thought I'm going to stab and I'm going to hurt these f---ing dogs," he said. "So I thought originally, look for rich areas. I thought rich areas, these f---ing c---s, they don't care unless it happens to them, unless it's in their society."
Price claimed he'd had the urge to kill for quite a while.
"I was planning this days before I went to Kew thinking of stabbing someone. I remember on the bus to that region; I was sitting next to these two Asian chicks; I was looking at them and just knew I was going to do something bad."
Price boarded bus 724 near the intersection of Victoria and Wellington Streets, Collingwood, at about 6.14pm to travel to the Doncaster park and ride bus stop on Doncaster Road. He arrived at about 6.35pm and began walking.
Ms Vukotic left her home to go for a walk about five minutes later carrying her front door key, mobile phone. She was listening to music on her earphones.
It was a sunny day and sunset wasn't until 7.30pm.
Ms Vukotic walked towards a small park called Koonung Creek Linear Park, about 1.6 kilometres south east of the Doncaster park and ride bus stop.
Price had entered the park and was looking for someone to stab when he saw Ms Vukotic.
"This chick was on the other side of the road ... she's like started talking to a bird like f---ing Snow White," Price later told police.
"I thought she's ... dressed like f---ing all yuppie.
"I just thought f--- this, this is the moment. This one just ended up being the one. I just f---en had to kill her."
Price said Ms Vukotic had ended up in the wrong place at the wrong time.
He took out the kitchen knife he had wrapped in a sock from his bag and ran up to Ms Vukotic.
Price pushed the terrified schoolgirl into bushes off the footpath so he could stab her.
Ms Vukotic pleaded with Price not to hurt her, telling him, "No, I'll do anything you want."
Price ignored her and began stabbing her repeatedly.
Price said he made sure Ms Vukotic was dead because "otherwise it was a waste of f---ing time doing what I'm doing."
Price then ran off carrying the knife, the bag and his jacket before using a tap from a house on Heyington Street to wash the blood from his hands, arms and face.
He put the spare T-shirt he had over the bloodied T-shirt he was wearing and boarded a bus on Doncaster Road at about 7.10pm.
Commuters noticed Price was agitated, nervous, out of breath and sweating profusely.
He got off on Victoria Street, Abbotsford, walked to Victoria Park railway station and caught a train to Flinders Street station before travelling to Sunshine station and walking home.
The next day at 7.07am, Price again left home intending to stab someone else.
He travelled from Footscray to Seaholme then back to Yarraville, where he got off the train at about 9.33am.
There he claimed he decided not stab anyone after a stranger gave him $50.
On his way home, he stopped in at the Brimbank library in Sunshine to go online to read media reports on Ms Vukotic's murder.
The next morning, two days after the murder, Price was in Sunshine when he grabbed a man around the neck, punched him in the head several times and stole his mobile phone.
Price then went back to the Brimbank library and spent 17 minutes reading more reports about the murder.
"More and more was coming out and I'm thinking, I'm f---ed now," he told police.
Price then tried to steal a BMW but the owner fought him off.
Realising it was only a matter of time before he was arrested, Price decided to rape someone.
"I thought f---, I'm going to jail for this one. I've just got to take a chick. I'm going to be stranded for the rest of my life. Who cares, no one's going to give me a Noble prize; I'm going to get a life sentence for this. I thought I'll bust a nut just before I f---ing go to jail forever."
Price walked into a nearby store at 11.10am and grabbed a woman, putting his hand over her mouth to stop her from screaming.
Price began choking the woman with both hands but she fought back, biting, pinching, poking and scratching him wherever she could. The woman attempted to gouge at Price's eyes and pushed her fingers into his mouth.
Price continued choking her before lying on top of her and rubbing his body up against hers.
Price began applying more force to the woman's neck when a customer came in and yelled out to Price to stop. Price ran off.
It was just a few minutes later when Price walked into the Sunshine Corrections office at 11.26am, smiled and declared, "I'm the Donny murderer."
