Law enforcement officers were flagged down just before 2 a.m. Tuesday that a man had been shot right outside the door to Palmas bar on Park Place Boulevard near Reveille Street.
Investigators believe the deadly shooting likely stemmed from an argument inside the bar.
Police said there were at least 10 people around when multiple shots were fired. Investigators found four shell casings on the ground.
The 48-year-old victim was shot several times and was pronounced dead at the scene.
Police said there are still unanswered questions about the moments that led up to the deadly shooting.
"It's not clear if [the argument] was between the suspect and the complainant, or if the complainant was just an innocent bystander who took the shots, or got shot outside the bar, or even might have gotten shot inside the bar," Det. Shawn Overstreet said.
Investigators said most of the witnesses left before talking to police and they were only able to talk to a bartender and the owner of the bar.
Detectives said they are hopeful they can gather surveillance footage in the area.
Investigators described the suspect only as a Hispanic man in his 20s or 30s. He fled the scene after the shooting.
Anyone with information in this case is urged to contact the HPD Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
