A husband who died alongside his wife in a head-on collision with a police van may have momentarily fallen asleep before the crash, an inquest has heard.

John Jackson, 60, had driven from Bwlchgwyn, North Wales, to RAF Brize Norton with his daughter Ffion to pick up his wife Nerys, 57, who had been working abroad.

The family were returning home when the fatal crash happened on December 9 last year, also seriously injuring the couple's daughter.

An inquest heard on Wednesday that Mr Jackson’s Skoda Octavia failed to negotiate a bend in the road on the A458 in Morville Heath, Shropshire, at around 10.15am and collided with an oncoming West Mercia Police Ford Transit crime scene investigation van being driven by Bethan Davis.

Ms David was also seriously injured in the collision attending the inquest at Shropshire Coroner's Court in a wheelchair.

Reading a statement by Ffion Jackson, senior coroner John Ellery said Mr Jackson had been “pottering” about the family home tidying up all day ahead of Mrs Jackson’s arrival back home from the Ascension Islands.

She said she believed he was still awake when she went to bed at around midnight, before he woke her up to start the car journey to Oxfordshire at around 4am.

She remembered driving through Stourbridge, but then her next memory was waking up “uncomfortable and confused” after the collision.

She added that her father had said he was “fine to carry on” when they had earlier stopped at Hopwood Park Services on the M42 to get a coffee and stretch his legs, and that he “wouldn’t have carried on if he didn’t feel safe to do so”.

Ronald Ball, who had been driving behind Mr Jackson on the A458 before the crash, said he saw the Skoda “straying across the central line” and travelling below the 60mph speed limit, and initially thought the driver may have been drunk, so he decided to overtake him to put some distance between them.

Holly Wainwright, who was driving behind Mr Jackson’s car at the time of the collision, said he had “drifted” across the white lines on to the other side of the road as they travelled towards a left-hand bend in the road, narrowly missing a vehicle that swerved out of the way, before the Skoda hit the police van.

Detective Sergeant Julie Lyman, of West Midlands Police, who investigated the collision as the vehicle involved a West Mercia Police van, said she believed Mr Jackson may have been distracted or had had a “micro-sleep” after a long drive and that the collision was “inevitable”.

Mr Ellery said Mr Jackson had not had any drugs or alcohol and had not been operating his phone before the crash.

Mr Ellery said: “The circumstances seem clear that Mr Jackson, while driving towards home, drifted into the path of the police vehicle.

“Ms Davis could not have avoided the collision.

“As to why Mr Jackson drifted across, I have to consider the evidence to answer that, and while there is no direct evidence, it seems most likely that Mr Jackson has fallen asleep.”

The coroner recorded that Mr and Mrs Jackson died as a result of a road traffic collision.
