DETECTIVES investigating a fatal crash are still searching for more witnesses to come forward.
Michael Brown, 43, was killed in the collision on the A31 between Winterbourne Zelston and Bere Regis last Monday, March 24.
He had been travelling in a Skoda with his wife, aged 37, and his seven-year-old daughter at the time.
Both received serious injuries, but have since been discharged from hospital.
A blue Subaru car travelling west overtook a heavy goods vehicle and collided with the Skoda, which was travelling in the opposite direction.
The Subaru also collided with a black Mercedes before coming to rest in the middle of the road, police said.
Dorset Police have urged the occupants of a small green hatchback to get in touch.
Police Sergeant Jon Wren, of Dorset Police’s Traffic Unit, said “During the early stages of the Subaru’s overtake it appears that a small green hatch back car may have been forced to take avoiding action.
"We would very much like to hear from the driver or passengers from this car. They are not implicated in the collision but may be important witnesses to our investigation. I would urge them to get in contact with police as soon as possible.
“Any witnesses that have not already spoken to the police should call the non-emergency number 101 and ask for PC 1294 Chris Smith from the Poole Traffic Unit.”
A 28-year-old man from Taunton was arrested on suspicion of causing death by dangerous driving and has been released on police bail pending further enquiries.
Witnesses and anyone with information should call Dorset Police in confidence on 101 quoting incident number 24:368. Alternatively, call the free and anonymous Crimestoppers line on 0800 555 111 where mobile phone tariffs may apply.
