The detective inspector leading the investigation into a fatal A350 crash near Trowbridge has not ruled out the possiblity the driver intended to commit suicide.

Latvian Valerijs Grigorjevs, 27, died instantly when the Toyota Yaris he was driving collided head-on with a Framptons Transport lorry between Hagg Hill and Stoney Gutter at 6.20am on October 11.

Dorset Police believe that hours earlier Mr Grigorjevs murdered car wash owner Ibrahim Youseuf, 42, at his home in Gloucester Road, Boscombe, near Bournemouth.

Detective Inspector Marcus Hester, of Dorset Police, said: “There’s no obvious reason why the car collided with the lorry, so that’s one for the coroner to consider and decide on.

“We are now compiling a file for the Crown Prosecution Service and the coroner will then make a ruling regarding the deaths of both men.”

The inquests of Mr Grigorjevs, from Heathcote Road, Boscombe, and Mr Youseuf will take place at Bournemouth Coroner’s Court on December 6.

Through Wiltshire Police’s initial investigations Dorset Police went to a property where the Yaris was registered, where they were told the car was owned by Mr Youseuf, originally from Iraq.

At Mr Youseuf’s home they discovered his body, which had two stab wounds and multiple head injuries.

His car had been stolen from outside his home.

DI Hester said: “We are certainly not looking for anyone else in connection with this murder. It is clear that these two knew each other but we do not know much about their relationship at this stage.

“Families of both the men have been informed of their deaths. They are both devastated and probably it is made worse by the fact that they are thousands of miles away.”

DI Hester said that the police did not have much information about Mr Grigorjevs’s background, but Mr Youseuf had lived in this country since the early 2000s, and had become a British citizen.

Police recovered two knives, believed to be the murder weapons, from Mr Youseuf’s home.

DI Hester said: “Our work with Wiltshire Police traffic department and crime team has been very productive throughout this investigation.”
