Police investigating a fatal road traffic collision just outside Milton Keynes on Wednesday evening (9 February) are appealing for witnesses.
Just before 9pm, officers were called to a report of a collision between a Heavy Goods Vehicle (HGV) and a pedestrian on the eastbound carriageway of the A421, between Milton Keynes and Junction 13 of the M1.
Sadly, the pedestrian - a man in his 50s - was pronounced dead at the scene. While he has not been formally identified, his next of kin has been informed.
Sergeant David Burstow, from the Bedfordshire, Cambridgeshire and Hertfordshire Serious Collision Investigation Unit, said: “Our thoughts are with the family and friends of the victim.
“We are trying to establish the circumstances of this incident as it is believed that the victim was initially in a vehicle which had suffered a tyre puncture, and he was walking along the carriageway to get help.
“I would urge anyone to contact us as soon as possible if you witnessed the collision or were driving along the A421 towards the motorway junction at that time and saw the pedestrian or their red Alfa Romeo car, especially if you have a dash cam fitted to your vehicle.”
