The homicide of a 22-year-old man in a downtown Edmonton parkade is also being investigated by provincial Occupational Health and Safety officials.

Occupational Health and Safety spokesperson Shanna Schulhauser confirmed Friday that the agency is investigating a Sept. 4 workplace fatality in which a restaurant worker was allegedly fatally injured by a worker from a delivery company.

Schulhauser added that the investigation remains active, and declined to share the names of the employers that the victim and accused worked for.

Earlier this week, Edmonton police announced that 40-year-old Edgar Wesker was arrested and charged with second-degree murder in the death of 22-year-old Jashandeep Maan.

EPS said that officers responded to a weapons complaint at about 12:15 p.m. on Wednesday in a parkade at 101st Street and 102nd Avenue. On arrival, they discovered the injured man, as well as the suspect.

EMS arrived and treated Maan, but he was declared dead at the scene.

Wesker was taken into custody. An autopsy has since determined Maan died of multiple sharp force injuries.

“We can confirm that both men were not known to one another, and this appears to be an isolated incident,” homicide section Staff Sgt. Colin Leathem said in a statement on Thursday.

“The accused remained on scene, was swiftly taken into custody by our officers and we have no additional concerns for public safety at this time.”

On Friday, police spokesperson Carolin Maran reiterated that investigators believe the attack was random.
