Female Audi driver high on ‘hippie crack’ nitrous oxide killed musician while talking to his father on the phone – after ramming into him at 60mph in a 20mph zone

A female Audi driver high on ‘hippie crack’ killed a musician while talking to his father on the phone.

Tiffany Treanor-Johnson, 27, had taken the Class C drug nitrous oxide, also known as nitrous oxide, and was driving at 90km/h in a 20mph zone when she struck Harry Webb, 27, and drove off.

Harry cycled hands-free with his parents and thanked them for helping them move around London just hours earlier in September 2023.

Treanor-Johnson, then 24, was driving more than double the speed limit when she struck Harry on the pavement, causing a traumatic brain injury.

She then drove away, leaving him fatally injured on the side of the road in Hackney. He died from his injuries two days later.

A motorist who saw the crash tried to stop Treanor-Johnson, who was in the car with two friends, from driving away, but was unsuccessful.

Harry’s parents Mike and Pat, both 66, listened to the horrific crash unfold on the phone.

A stranger then answered their son’s phone after hearing Mike’s screams and told them that their son had been hit by a car.

Tiffany Treanor-Johnson, 27, was high on the Class C drug nitrous oxide and was driving at 90km/h in a 32km/h zone when she struck 27-year-old Harry Webb and drove away in September 2023. He died two days later

Harry Webb, 27, was on the phone to his parents in September 2023 thanking them for their help moving around London when Treanor-Johnson hit him with her Audi.

Mike said: ‘The passerby we spoke to told us Harry had his helmet on. He was trying to reassure me, I think, but we could hear the sirens.

‘We were then told that an ambulance had arrived and would take Harry to hospital.

“We both put some stuff in a bag because we thought he had a broken leg or something.

‘That was until a surgeon from the hospital called us. They told us to stop, so we did. Then we were told that Harry had suffered severe brain trauma and was unlikely to survive.

‘He died two days later surrounded by his family and about twenty of his friends.

“He just called, ‘Thanks mom, thanks dad’ for helping with the move.”

The collision took place on Kenworthy Road, Hackney, a road notorious for road accidents.

Mike said campaigns had been going on for 15 years to make the road safe where his son was killed.

Harry, who studied music production at the London College of Contemporary Music, was cycling to London Fields Lido for a swim when the accident happened.

Treanor-Johnson changed her plea to guilty on the day of the trial and admitted causing death by dangerous driving. She initially pleaded not guilty.

At the time of the crash, possession of nitrous oxide was not illegal in Britain.

It was reclassified as a Class C drug on November 8, 2023.

Mike said Treanor-Johnson showed “no remorse” for killing his son.

“She completely denies what she did,” he said.

Harry’s mother Pat was also shocked by the lack of remorse after her son’s death.

She said: ‘After all this time, we haven’t heard anything from her or her family – not even an ‘I’m sorry’ or a ‘I’m sorry for your loss.’ Nothing.

‘It was all about her, about how difficult her childhood was and other things, while we are the victims – our son is dead. He has been robbed of his future.”

Judge Rosa Dean remanded Treanor-Johnson in custody and adjourned sentencing at Snaresbrook Crown Court until July.

The judge said: ‘It appears you have tried to bury your head in the sand and left it to the day of the trial to accept that you have no defense and accept responsibility.

‘You are facing a substantial prison sentence. It seems to me that there is a significant risk that, if I were to grant you bail, you would once again bury your head in the sand.’
