Officers responded at 1:30 a.m. to the altercation, which began inside a bar at 1050 S. Wadsworth and escalated outside.
Police found a 34-year-old man lying in the parking lot, injured. Detectives learned the victim had been asked to leave the bar after becoming "belligerent", but returned anyway.
According to police, the victim was intoxicated when he got into the fight with at least one other person.
Detectives are interviewing one of those people involved in the fight to determine the exact cause of death.
Once the Jefferson County Coroner's Office completes their investigation, police will determine whether charges are appropriate.
