Hertford hit-and-run victim's photo released by police
Police investigating the death of a man in a hit-and-run collision in Hertfordshire have released a photo of the victim and more details about him.
David Alderson, 66, was found by a cyclist at the side of the B1000 Welwyn Road, close to Sele Farm, Hertford, on Wednesday morning.
Mr Alderson is believed to have been struck between Tuesday evening and the early hours of Wednesday.
He lived at Broadwater Crescent in Welwyn Garden City.
Mr Alderson, whose body was found at 06:50 BST, was 5ft 3in (1.6m) tall and slim with grey hair.
He was wearing dark grey or black jogging bottoms, a light blue polo shirt, black trainers, a navy blue anorak with a green lining and dark grey or black woollen gloves.
He may also have been wearing a dark woollen hat.
Insp Andy Piper from the Bedfordshire and Hertfordshire road policing unit said: "We're trying to piece together David's last movements.
"He was last seen at 10:00 on Tuesday in Welwyn Garden City and I would like to speak to anyone who may have seen him after this time or knows what he may have been doing in Hertford that afternoon or evening."
He appealed for anyone who saw Mr Alderson walking along the B1000 to contact police, along with anyone who either saw or heard the collision or saw a vehicle pulled up at the side of the road.
"I would also appeal to the driver of the vehicle to come forward," said Mr Piper.
"You may not have realised you had struck a man or had been involved in a collision.
"While this investigation is in its infancy I would urge you to call police as it would be in your best interest to come forward as soon as possible."
Anyone with any information is asked to contact Hertfordshire Police or Crimestoppers.
