Disturbed killer Jamie Lee Dolheguy lured a man she met on an online dating app to her Melbourne home where she choked him and wrapped a sex toy cable around his neck.
The 21-year-old was found guilty of manslaughter after she killed international student Maulin Rathod in July 2018.
She was jailed for nine years on Thursday after being found guilty of manslaughter at a trial in the Victorian Supreme Court last year.
But Dolheguy will be eligible for parole after five years and six months and, with time served, could be out in three years and three months.
The pair met on the dating app Plenty of Fish, and after briefly exchanging messages, Dolheguy convinced the 24-year-old to come to her Sunbury house for sex.
They agreed to “choke play” where Dolheguy, who was then 18, wrapped her arm around Mr Rathod’s neck from behind, and despite the student’s signal to stop, she continued to hold him.
“It will be OK,” she whispered to him.
The killer wrapped the cable of a sex toy around her victim’s neck and tightened it before she called police for help. Mr Rathod later died in hospital.
While she waited for her victim to arrive at the home she went online and searched “I’m going to kill someone tonight for fun”, the court was previously told.
Dolheguy even visited a website called “ten steps to commit a murder and get away with it” before he arrived.
But the victim’s heartbroken family struggled with the loss of their son who was months away from graduating.
“He is a victim of that girl trapping him,” parents Hiren and Jagruti Rathod previously said in a statement.
The extreme abuse and neglect Dolheguy suffered at a young age left her with a severe personality disorder, and she felt no empathy or remorse for her victim, the judge said.
She was removed from her home at age 10 because of the horrific conditions and had two full-time carers from the age of 14. When she turned 18, however, this was removed, and she was left to live alone.
Barrister Sharon Lacy previously told the jury during the trial that Dolheguy was “damaged” and her mind was “chaos” at the time of the killing, and there was no way they could be satisfied of murderous intent.
However, Justice Almond noted in his sentence there had been an improvement in her condition, and an expert found there was room for “cautious optimism” for her rehabilitation.
Her lawyers had previously argued because of her young age and disturbed personality she should be jailed in a youth facility. This was rejected, and she will be jailed at an adult prison.
During the trial there was no dispute about whether Dolheguy killed Mr Rathod but whether she intended to do it.
