Jose Monzon, 37, was killed in the parking lot of Club Imperial in East Tulsa after a late-night brawl that began inside the club on the night of June 21, 2014. The club closed about 2 a.m., a very large fight between members of two rival gangs spilled outside, and the melee reignited in the lot. Amid the chaos — people scattering and a car striking a security guard — Monzon, who investigators believe was the father of one of the young men involved and not himself a gang member, was stabbed once in the chest. Emergency crews performed chest compressions at the scene, but he died of the wound.

Tulsa homicide detectives interviewed many witnesses and identified most people who were there, and they isolated at least two people of interest, but police described witness cooperation as minimal and said there was not enough evidence at that time to arrest anyone for murder. Physical evidence was submitted to the Tulsa Police Forensic Lab and the investigation remained active. Does anyone who was at Club Imperial that night or who knows more about the parking lot confrontation have information to share?
