EDMONTON -- Homicide detectives are investigating a suspicious death that happened on Christmas morning.

Officers received reports about shots fired in the area of 117 Street and 107 Avenue around 7:20 a.m.

A 28-year-old man was found outside an apartment building there. He was treated by paramedics, but died at the scene.

Several people were seen leaving the area in vehicles. Police want to speak to anyone who was present at the time of the incident.

On Thursday, Edmonton Police Service members spent part of the day interviewing residents of the neighbourhood.

Neighbour Michelle Jaudrey told CTV News Edmonton she heard from her bedroom sounds like firecrackers Christmas morning.

"Police cars had pulled up in different angles and an ambulance had showed up," she recalled of the moments after the noise.

"That's when I saw someone lying on the ground and one of the EMTs started to do what looked like very aggressive CPR to me."

She added she saw two young women who were "extremely upset" near the scene.

On the fourth floor of the apartment building, Evan Jarock said he had heard commotion coming from a unit across the hall. About 20 minutes later, he estimated, he saw police leave with a man from the apartment.

EPS has not confirmed whether anyone has been arrested or charged.

Both Jarock and Jaudrey said the incident has been hard emotionally.

"It's Christmas. Overall, it's a tough situation," Jarock said.

Jaudrey added: "You're watching someone's life... just be over."

Anyone with information about what led up to the shooting is asked to call police at 780-423-4567 or Crime Stoppers at 1-800-222-8477.
