The mother of a man who died in a road accident in Hertfordshire has appealed for help to find the man suspected of driving the car.
Pedestrian Ricky Burlton, 20, from Enfield, died early on 4 June on the A10 exit slip road at Hoddesdon.
Police believe a man known as Georgios Tsoulos was driving the car.
Mr Burlton's mother, Dawn Burlton, said somebody knew the whereabouts of Mr Tsoulos, adding: "I plead with you to pick up the phone and call the police."
On the day of the collision, Mr Tsoulos was transferred from North Middlesex Hospital to Chase Farm Hospital in Enfield where he was treated for injuries to his face.
He was due to be transferred to Moorfields Hospital in London for further treatment to an eye injury but has not been seen since.
Mr Tsoulos is believed to be Albanian and living in the UK under a false Greek identity.
A video appeal by Mrs Burlton has been made and posted on YouTube.
She said of her son: "He had everything to live for and has been so cruelly robbed of his future and dreams."
She said that following the initial collision, Mr Burlton was hit by multiple vehicles "to the effect that I was unable to see Ricky, to touch and to hold Ricky or to kiss Ricky goodbye".
"But what I do know is somebody knows Georgios Tsoulos, what his true identity is or where he is.
"I plead with you to pick up the phone and call the police or Crimestoppers so that in his death my darling first born son Ricky can receive the respect and justice he so truly deserves."
