An expert from the UK told a court that he believed a teenager who died in a traffic collision fell into the incoming lane before being knocked back by a vehicle.

Michael Prime, a collision expert witness for the defence, told the court yesterday that while a scratch mark in the road suggested Jen-Naya Simmons was riding in the eastbound lane, she most likely fell into the westbound lane after she lost control of her bike.

“We know that Ms Simmons fell off the motorcycle to the right,” he told the Supreme Court. “For the scratch to start in the eastbound lane, we know the motorcycle must have been in the eastbound lane when it fell over.

“When anyone falls off a motorcycle, if the motorcycle falls to the right, the rider will fall to the right of it and inevitably they will part company with it.

“With the scratch marks being so close to the centre line it would be no surprise for Ms Simmons to fall into the westbound lane.”

Mr Prime said that he believed Ms Simmons was struck by an incoming vehicle while in the westbound lane and the impact moved her back into her lane.

“I find it no surprise that she was displaced back into her original lane of travel and I find it no surprise she ended up in the eastbound lane close to the centre line,” he said. “How far back she was pushed, we don’t know.”

The court also heard that a report from a government analyst had discovered alcohol and MDMA – commonly known as ecstasy – in Ms Simmons’s body after her death.

The report said that while blood samples were not available, samples from her vitreous humour revealed 97 milligrams of alcohol within 100 millilitres of blood.

The report added that the alcohol levels in the vitreous humour do not directly correlate to the alcohol level in a person’s blood stream, but the reading was consistent with a blood-alcohol level of between 96mg and 129mg of alcohol within 100ml of blood.

The legal blood-alcohol level for drivers in Bermuda is 80mg of alcohol in 100ml.

Tests also revealed levels of MDMA within Ms Simmons’s liver and urine, which indicated that she had taken the drug at some time before her death.

Terrance Walker, from Pembroke, has denied a charge that he caused the death of Ms Simmons by careless driving in the early hours of July 15, 2018.

He declined to take the stand yesterday in his own defence.

The court previously heard that Ms Simmons was on her way home from a house party in Warwick when the fatal collision occurred on North Shore Road in Hamilton Parish.

Glenn Luben, a US traffic collision expert, earlier said the evidence suggested Ms Simmons lost control of her auxiliary cycle and was struck and killed by an incoming vehicle in her lane.

Jada Simmons-Trott, a friend of Ms Simmons, said she had seen a grey or white coloured van moving west in the area partially in the eastbound lane moments before she lost track of her friend.

She told the court that Ms Simmons had several shots at the house party and had fallen off the vehicle earlier in the evening, but did not appear to be impaired and had driven properly before the fatal collision.

Asked in cross-examination if Ms Simmons had taken MDMA on the night of the crash, Ms Simmons-Trott said she had not seen her do so.

Another witness said she had seen a silver van travelling west turn off its lights moments before she came across the scene of the collision.

A silver van was identified on CCTV footage on North Shore Road near the time of the collision and was found to be registered to Mr Walker.

Mr Walker later told police that he was the usual driver of the vehicle, and that the van had been involved in a “fender bender thing”, but denied that it had been involved in an accident.

The trial continues.
