Marc Williams death: Parents appeal to find hit-and-run driver
The parents of a man who died after a hit-and-run in Berkshire have urged to the driver to explain what happened.
Marc Williams, 22, died on 1 December after he was found lying on a slip road for the A404M at Cox Green.
Officers believe he was hit by a car which failed to stop between about 02:15 and 02:30 GMT.
Fighting back tears, Mark Williams and Joanne Parker described in a video posted on You Tube how they are still coming to terms with losing their son.
Mr Williams said: "You cry yourself to sleep every night because we don't know what's happened. We need to know what happened.
"Our son Marc was a lovely, lovely boy. He was so gentle, so kind, so joyful, always smiling.
"You could understand perhaps, if somebody had this collision and the fear, at the spur of the moment, might make you not stop.
"But surely the next day or the day after you'd come forward.
"You wouldn't leave a dog on the side of the road and Marc has been left on the side of the road."
Police are still trying to trace a silver Vauxhall Astra and a black Mercedes E or C class saloon captured on CCTV near the scene.
They were seen turning into Shoppenhangers Road from King Street at about 02:20 GMT.
Mr Williams, who worked as a epilepsy support worker, had been in Maidenhead to see a friend's band on the night he died.
After leaving a pub in the town centre at 01:00 GMT, he was last seen on CCTV passing a taxi rank at the railway station shortly after.
He was found by passer-bys and died from his injuries en-route to hospital.
