Teenage speedway champion Tyler King who stabbed his sister’s abusive boyfriend Jesse Tattersall to death discovers his fate

A former teenage speedway racing champion has been convicted of murdering his sister’s abusive boyfriend after he bragged: ‘You should see what I do to her in the bedroom’.

Newcastle High Court Judge Natalie Adams said on Thursday she could not say whether Tyler King intended to kill Jesse Tattersall and convicted him because he wanted to cause Tattersall grievous bodily harm in the hope he would never hurt his sister again .

After stabbing Tattersall twice, King told his sister: “Nobody’s going to hit you again, nobody’s going to hurt you again,” before stabbing Tattersall a third time.

King, 27, from Budgewoi, pleaded guilty to the manslaughter of Tattersall, 33, at Hamlyn Terrace on September 8, 2022.

Judge Adams said King claimed that, from his perspective, his sister Tenille was violently attacked by Tattersall and that he had to do something.

“Tenille told him she was afraid of the deceased and asked him to come to the house to protect her,” the judge said as he jailed King for six years and nine months, with a minimum term of four years and three months.

“The deceased then entered her property through a security door and immediately began violently attacking her. She was defenseless against this attack.”

When King confronted Tattersall just after 8.10pm as he dragged his sister around the living room, Tattersall said: ‘Sorry bro, sorry bro. I won’t hit her again.’

Tattersall, a father-of-two, smashed King’s head through a plasterboard wall before telling him: ‘You should see what I do to her in the bedroom.’

King, who was on bail for aggravated burglary, grabbed a knife from the kitchen as the pair fought and he stabbed Tattersall three times as Tenille tried to separate them.

Tattersall, who threatened to kill Tenille after an argument earlier in the evening, staggered out of the house, collapsed and died outside a neighbour’s house.

Judge Adams said it was clear that Tattersall intended to attack Tenille and she accepted that King had acted out of fear and panic to some extent.

“At the time of the deceased’s attack on Tenille, the deceased undoubtedly believed that she was alone in her home and that he could attack her freely. There was no evidence. When he physically assaulted her, he knew Mr. King was present.

‘It is a hallmark of domestic violence that it often takes place at home without witnesses.’

The judge noted that King was a talented speedway racer from a loving family who left school and traveled to the United Kingdom to compete professionally at the age of 15 on a one-year contract, but did not have the success he expected.

He returned to Australia, never went to school again and his life spiraled out of control when he became addicted to drugs.

After stabbing Tattersall, King’s then girlfriend, Maddison York, 21, called an Uber and the pair fled the scene before being arrested in Gorokan.

York, who pleaded guilty to accessory after the fact in the murder, was convicted Thursday but was allowed to spend 19 months in prison after her arrest.
