But Jazmin hadn’t been in a car crash, she had been savagely beaten and kicked to death by her 25-year-old ice-fuelled boyfriend.

This sobering assessment was delivered at the 2013 trial of Sean Lee King who was sentenced to 32 and six months years jail for the murder of his 18-year-old girlfriend in her inner-city apartment.

King’s lawyer at the time, veteran defence lawyer Gregory Goold, told The Daily Telegraph his client was completely under the spell of ice at the time of the murder and in the aftermath was horrified by his actions.

He said King had been in a type of drug-fuelled psychosis as he beat the life out of Jazmin and said his use of ice had stripped him of any control he had over his actions.

“Sean had been smoking ice regularly leading up to the violent death of the victim and it seems that regular use of that drug leads to an inability to control behaviour,” Goold said.

“He was always adamant he didn’t intend to kill her but there were certain things he did in the lead-up to killing that poor girl that lead the jury to find him guilty of murder.”

Ice, which over the past decade has become a huge burden on law enforcement and health resources across the country, is known to cause psychosis in heavy users and leads to some users experiencing extraordinary strength.

It also instils a sense of unfounded paranoia in some and can bring on violent and aggressive behaviour.

“If people are getting into fights or arguments, they seem to have extreme strengths and are very aggressive,” National Drug and Alcohol Research Centre’s Dr Sharlene Kay told The Daily Telegraph.

“People (become) very agitated, very physically active and seem to be very strong.”

This may go some way to explaining the extreme force King used during his brutal attack.

A TUMULTUOUS RELATIONSHIP

King and Ajbschitz met at a music festival in 2009 and soon after started dating.

During the murder trial the court heard the relationship was volatile, with King responsible for a number of violent outbursts towards Jazmin.

The night before her murder, they spent the night together before Jazmin returned home the following morning. The pair then exchanged a number of text messages during the day.

Consistent with their relationship, the messages displayed the volatile tendencies of King, eventually leading to Ajbschitz seemingly deciding to end things.

King, who was on parole, then smoked ice before angrily calling Jazmin.

A friend, who heard the phone conversation on loud speaker, gave evidence that King threatened Jazmin, telling her: “I’m going to f***ing kill you. Wait until I see you. You don’t know what I can do”.

“You think I’m joking ... I’ll kill you and then anybody else that you’re with”.

Jazmin’s mum, staying in Perth for work, had told her over the phone she would be safe in their locked building but warned her to barricade the apartment door just in case.

A FATAL MISTAKE

King and two friends then drove into the city from his home in Campbelltown, having smoked more ice on the way, Jazmin came down to talk to him through the locked glass doors of the building.

CCTV footage captured the tragic final moments of the teenager’s life and showed the fatal mistake she made letting King inside the security building where she lived.

It was the last time she was seen alive.

About 26 minutes later King was captured on CCTV returning to the foyer alone, his jumper hood pulled over his head and his sleeves pulled down over his hands.

Neighbours reported hearing thudding noises from Jazmin’s apartment, another describing the sound as a ‘slow thump’. This went on for about three minutes.

When Jazmin’s body was discovered in the Ultimo apartment her mum owned, police found a scene of a frenzied and sustained assault.

Blood was splashed over the walls and on the carpet in multiple rooms and furniture had been upturned. King had repeatedly and viciously stomped and kicked her to death.

Goold said King’s almost immediate remorse was evident when he tried to get help for Jazmin who lay dying from injuries to almost every inch of her body.

“He tried to call for an ambulance with a friend but he was still so off his face he didn’t know what he was doing,” he said.

King had in fact got a friend to call for paramedics but in his psychotic state had got the address to the apartment wrong.

An ambulance never arrived.

A TROUBLED CHILDHOOD

King’s parents separated when he was three years old after his father attempted to drown him.

Despite this incident, and King and his mother moving away, his father made a number of attempts to gain custody.

Leaving school at the age of 15, King worked various labouring jobs.

Drugs had a major impact on his life. He first began using drugs as a teenager, smoking ice for the first time at 18. It was at this point that King had a son. He maintained contact with the boy until he murdered Jazmin. He has since indicated his desire to be a father but has had little or no contact with his son since the violent attack.

While Justice Bellew found that King was remorseful after the attack he handed down a non-parole sentence of 25 years and six months.

The jury rejected King’s his claim that he was so high on ice that he was unable to form the intent to kill.

King subsequently appealed but the case was dismissed by the NSW Court of Criminal Appeal.

In his four decades as an lawyer, Mr Goold said he had only one other murder case that had resulted in such a harsh sentence.

“King’s sentence was above the standard non-parole period of 20 years meaning Justice Bellow believed the attack to be more brutal than usual,” Mr Goold said.
