A woman from Bournemouth has been found guilty of murder after deliberately driving into a motorcyclist.
Zoe Treadwell, 36, was convicted of killing 28-year-old Joey Johnstone after hitting him with her car in South Kinson Drive in Bournemouth in April this year (2025).
She was also found guilty of attempting to murder a second man and causing grievous bodily harm with intent to a third man, following a second collision in May 2025.
A second defendant, Jonjay Harrison, 25, from Bournemouth, was also found guilty of attempted murder and grievous bodily harm with intent in relation to the May collision.
The first collision happened in South Kinson Drive during the early hours of 9th April 2025.
It involved two electric motorbikes being chased at high speed by a Range Rover, which subsequently struck one of the bikes and knocked the rider from it. The driver of the Range Rover did not stop.
The motorcyclist, 28-year-old Joey Johnstone from Bournemouth, was pronounced dead at the scene having suffered a traumatic head injury.
The second collision took place on Kinson Road on 1st May 2025, involving a Mercedes mounting the pavement and hitting an electric motorbike., knocking the rider and pillion passenger from it. The Mercedes then drove away from the scene.
The rider, 33-year-old Joshua Lovell, suffered multiple fractures. His pillion passenger, 30-year-old Free Jenkins, faced life-changing injuries including the amputation of part of his leg.
Wiltshire Police launched separate investigations into both collisions, which included carrying out CCTV trawls, taking numerous witness statements, analysing DNA samples taken from the involved vehicles, and completing vehicle speed analysis using gathered CCTV and ring doorbell footage.
Police say shortly after a connection between the two investigations was established and they were joined together.
Four people were subsequently arrested and charged in connection with the joint investigation:
- 36-year-old British national Zoe Treadwell, who defines herself as being of white British ethnicity
- 18-year-old British national Taylor Warwick, who self-defines his ethnicity as being of any other black background
- 25-year-old Jonjay Harrison, who defines himself as being of white British ethnicity
- A 17-year-old boy who cannot be named due to legal reasons
A trial began at Winchester Crown Court on Monday 27 October 2025.
Prosecutors said in both collisions, the young men riding e-bikes were chased by cars through residential roads before being driven into deliberately – a plan engineered by the four defendants as a result of a “long running grudge or feud”.
Warwick and the 17-year-old boy were accused of murder and manslaughter relating to the death of Mr Johnstone but denied being in the Range Rover at the time of the collision and denied assisting or encouraging Treadwell in causing the collision.
They were found not guilty.
After deliberations lasting 33 hours, jurors delivered their verdicts today (December 4) Treadwell and Harrison will receive sentences at a later date.
Detective Inspector Mark Jenkins, of Dorset Police’s Major Crime Investigation Team, said: “The sad death of Joey Johnstone came as a result of a deliberate, targeted and senseless attack which occurred during the early hours of Wednesday 9 April 2025.
“Mr Johnstone was pursued by Treadwell in a Range Rover around the streets of West Howe, because of a grievance which had arisen between one group of associates and another.
“This extreme aggression resulted in the tragic death of Joey that night. It then continued the following month, seeing a second deliberate collision occur which resulted in serious injuries for Joshua Lovell and devastating, life-altering injuries for Free Jenkins.
“The investigation team has worked extremely hard since the Joey Johnstone’s death to gather all the evidence available to them so that those responsible could be brought before the courts to face justice for their actions. I would like to thank everyone who worked on the case, as well as the Crown Prosecution Service and the prosecution team for presenting the evidence gathered in the best way possible.
“Finally, our thoughts remain with Joey Johnstone’s partner, three young children and the rest of his family and friends.”
Chief Inspector Barry Gosling, of Dorset Police, said: “We fully understand that this case would have had a significant impact on Bournemouth residents and specifically the West Howe community.
“At the time of the incidents, detectives conducted thorough investigations while officers carried out high visibility patrols in the vicinity to offer public re-assurance.
“We would like to assure people that our measures to protect our communities will not stop. We will continue to do all we can to tackle violent crime and I hope this case demonstrates that we will do everything in our power to ensure offenders are identified and held to account.
“Officers will continue to patrol the area and can be approached by members of the public with any concerns.”
