Frightening details emerge about moment ex-speedway racer killed his sister’s abusive boyfriend: ‘No’s one’s going to hurt you again’

A former teenage speedway racing champion killed his sister’s abusive boyfriend ‘out of panic and fear’, a judge has been told.

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

Prosecutor Brendan Queenan told Newcastle High Court on Friday that King showed his sister Tenille how he planned to kill Tattersall because of what he had done to her.

But defense attorney Peter Krisenthal argued that King would not have let Tattersall leave the duplex to get help from a neighbor after he was stabbed if he had intended to kill him.

Mr Krisenthal said King, 27, of Budgewoi, who pleaded guilty to the manslaughter of Tattersall, 33, at Hamlyn Terrace on September 8, 2022, was remorseful and understood the impact his actions had had on his victim’s family.

“The crime was reactionary and born of panic and fear,” the lawyer said.

King, 27, from Budgewoi, pleaded guilty to Tattersall’s manslaughter on September 8, 2022

“By any objective analysis, there was hostility and volatility on the part of the deceased, and his behavior was unpredictable and aggressive.”

Mr Krisenthal said King was a talented speedway racer who left school and traveled abroad to compete at the age of 15 on a one-year contract but did not have the success he expected.

He said King returned to Australia and his life spiraled out of control when he became addicted to drugs.

Tattersall, a father-of-two, was killed when he arrived at Tenille’s home just after 8.10pm after she told him her brother was upset because she chose Tattersall over her family.

Tattersall kicked open the front door, grabbed Tenille by the back of the head and punched her in the face.

He started dragging Tenille around the living room when King pulled him off his sister.

Tattersall smashed King’s head through a plasterboard wall and told him: ‘You should see what I do to her (Tenille) in the bedroom’.

King grabbed a knife from the kitchen as the pair fought and stabbed Tattersall three times as Tenille tried to restrain him.

Tattersall staggered out of the house and collapsed at the front of a neighbor’s house.

Paramedics were unable to revive him.

King and his then-girlfriend Maddison York called an Uber after their flight, but were later found in Gorokan.

York has pleaded guilty to accessory after the fact to the murder.

Tattersall’s mother Donna said in a victim impact statement that King had no right to take the life of her beloved and incredibly precious son.

Mrs Tattersall said she arrived at the scene and saw her first-born son ‘lying on that cold concrete, covered in blood, as a number of paramedics tried to save his life’.

“These images haunt my thoughts, just like the images of my boy lying on a cold, steel autopsy table.”

Judge Natalie Adams will sentence King and York on May 23 and ordered York released on bail after already spending 19 months in jail following her arrest.
