The victim, named locally as Jamey Coleman, was hit by a car on the A5 Watling Street in Brownhills at about 3.20am yesterday. He later died in hospital.
Flowers have been left at the scene, at the junction of White Horse Road, while police have installed a sign appealing for information. Mr Coleman is said to have been walking with friends from the White Horse pub yards away when he was hit. The pub opens until 3am on Saturday nights for a disco.
Friends rushed back to the pub after the crash to raise the alarm, while others tried to help him as he lay at the roadside.
Mr Coleman, believed to be in his mid-20s and known as 'Jay C', lived in Brownhills with his family.
A Facebook page has been launched by the victim's relatives appealing for information. It claims that Mr Coleman was killed in a hit-and-run, with the message: "If your partner, son, daughter, friend, friend of friend has a smashed front end of their car please contact your local police."
A man living near the scene of the tragedy paid tribute to Mr Coleman and said he was often seen on nights out in the area.
He said: "He went to Brownhills School, where I went, and I always used to see him around.
"He always had a smile on his face and was a cracking lad. He was always jolly. It's terrible what's happened."
One of the tributes left at the scene says: "Love and thoughts are with all that knew and loved Jay C. He will forever be remembered by all that knew him. He was a kind and loving and funny man full of energy and happiness."
Meanwhile a teenage girl suffered a serious head injury when she was hit by a car on the Black Country Route, between Bilston Market and Morrisons at around 6pm on Saturday. The girl, who was taken to hospital, is believed to be 15.
Those with information should call police on 101.
