Mr Haughton was in Valley Road, Park Village, at 9.10pm when he was shot in what West Midlands Police detectives understand was a targeted attack.
He was pronounced dead in hospital in the early hours of Saturday morning and a post mortem examination confirmed he died from a gunshot wound.
Detectives from West Midlands Police's Homicide Unit have been working throughout the weekend to understand the circumstances behind the shooting and to trace the man responsible.
Senior Investigating Officer, Detective Chief Inspector Chris Mallett, said: "We have a team of officers working on the case to find the person responsible and several lines of enquiry are being pursued.
"A young man has lost his life and I would urge witnesses, anyone with information, or anyone who was in or near Valley Road on Friday night and saw anything suspicious to contact us. Their information could be crucial.
"People can provide the information anonymously: they don't need to leave their names, we just want the information to get justice for this killing."
A tribute on behalf of Mr Haughton's family and partner described him as "caring, loving and thoughtful" and that he would have made the "perfect father".
It reads: "You have left a big hole in all of our hearts. We will forever miss your beautiful cheeky smile and infectious laugh. Love and miss you son, grandson, brother, uncle, nephew and cousin.
"You were the most caring loving and thoughtful boyfriend and would have been the most perfect husband and father.
"We love you more than words can show, I think about you more than you could ever know. Until forever this will be true, because there is no one I would ever love the way I love you.
"If tears could build a staircase and memories a lane I'd ride up to heaven and bring you home again."
Additional uniformed officers and armed police have been patrolling near the murder scene over the weekend to reassure the public.
Anyone with information is urged to call the Homicide team on 101 − quoting log 2914 of 20 July − or to contact the independent charity Crimestoppers anonymously on 0800 555 111.
