I knew a lad involved in a hit and run once. Involved as in the perpetrator. He was 16 at the time, living in Southern Africa, and was driving home from a club having consumed several drinks. He hit a security guard on a bicycle, stopped to see what had happened, and then panicked and drove off, leaving the mortally wounded guard in the road. He then rang an ambulance from a gas station some time later to say he'd seen a body in the road.
The guard was conscious but knew he was dying. He had memorised the numberplate and managed to get his pen out of his tunic pocket and wrote it on his hand. He tried to crawl off the road and got as far as the verge, and then died. He was found by a taxi driver the next morning, who called the police.
The 16-year-old decided to flee the country. He got as far as the border and was stopped by customs who were suspicious of the damage to his car. They called the police, who matched the registration with the one written on the guard's hand. The driver was arrested and eventually sentenced to 6 years in prison for manslaughter. After 3 years he died, aged 19, apparently of AIDS.
