Police have now identified a 30-year-old Markham man who they say died under suspicious circumstances on Monday evening.

At around 5 p.m. Monday, York Regional Police were called to an address on Stirling Crescent, near Denison Street and Aldergrove Drive, in Markham for a report of a pedestrian struck in the area.

When officers arrived on scene, they found a man, who has been identified as 30-year-old Michael Khan, unconscious. He was rushed to hospital but later died from his injuries.

On Monday night, police said the death had been deemed "suspicious."

The homicide and major collision units are handling the investigation, which police said is in its early stages.

Const. Andy Pattenden said investigators are awaiting the results of a post-mortem exam, which will be conducted today and will confirm the cause of death.

“From there we should be able to determine whether this is a fatal fail-to-remain collision or a homicide investigation," Pattenden told CP24 Tuesday.

"Really what we are trying to figure out is what led up to this man’s death."

York Regional Police have released a photo of a U-Haul vehicle that could be connected to the investigation.

“We know it was in the area at the time of his death. So we really want to find out who was driving that vehicle and where that vehicle is,” Pattenden added.

"We don’t have a license plate on that vehicle but we are hopeful anyone that may have been driving in the area, might have picked up that vehicle on a dash-cam. If they have that vehicle on a dash-cam, we’d like to hear from them.”

Officers have been canvassing the neighbourhood and Pattenden said police have "secured a lot of evidence" from the area.

"We will be talking to all the witnesses that were there. There were a number of people there," he said. "Some witnesses have come forward and spoken with our investigators but we know there are more people out there."

On Tuesday afternoon, Michael’s family released a statement calling him “a wonderful son,” and “the light of our world.”

“We are completely devastated by this tragic loss of a young man’s life. We ask for privacy as we grieve together as a family and appeal to the public to come forward with any information they have that may help in the investigation. We want justice for Michael and we want to see whoever did this behind bars.”
