It happened around 1:30 a.m. at Xhale Lounge, a hookah bar on 101 Street south of 82 Avenue.
Police said there was an altercation in the bar prior to the shooting. Shortly after, police believe a man approached the bar from outside and fired several rounds through the windows before fleeing. Several people were inside at the time.
Officers arrived to find a man dead inside the bar. Police said two other men, aged 23 and 32, sustained non-life-threatening injuries in the shooting. (Edmonton police at first said two people were killed, but later clarified that only one person had died.)
Bruce Conway with Alberta Health Services said EMS responded within 10 minutes of the shooting, but the victim was dead by time they arrived so the person was not taken to hospital.
An autopsy Tuesday determined Abubeker Gemechu Abduraman, 26, died from a gunshot wound. His death has been deemed homicide.
Bullet holes could be seen in the window of the bar, where homicide detectives were on scene investigating. Police expected that process to continue into Sunday evening.
On Sunday afternoon, an entire city block was cordoned off with police tape, from 101 Street to 102 Street, and from 81 Avenue to 82 Avenue.
Evidence markers were on the sidewalk in front of the lounge, and at least 10 EPS cruisers were parked around the scene.
The building was formerly the home of Wunderbar Hofbrauhaus, a live music venue that closed down a few years ago.
As of Tuesday afternoon, police said they did not have anyone in custody in connection with the shooting.
Investigators asked anyone who witnessed the shooting to contact police.
