The man shot and killed by a police officer at a traffic stop in southwest Edmonton Thursday has been identified as Vitaly Savin, sources tell CBC News.

An employee of an Edmonton home construction company where he had worked, confirmed he worked there as a subcontractor.

Savin's LinkedIn page says he's worked for more than eight years in Edmonton as a drill operator with the company, called Great Canadian. Prior to moving to Edmonton, he worked as a mining engineer in Russia.

On his Facebook page, Savin, 55, is still connected to family and friends in Russia.

The post was made around the time a Russian team was wrapping up a soccer game in the Europa League.

A court check shows Savin as having no criminal record.

At around 1:30 p.m. Thursday, Edmonton Police Service received two 911 calls from citizens reporting a possible impaired driver.

A patrol officer, driving a marked police vehicle, located the suspect vehicle in a cul-de-sac near Hollands Landing in the Hodgson neighbourhood in southwest Edmonton.

The officer pulled over the driver. Both got out of their cars. There was a confrontation, the Alberta Serious Incident Response Team (ASIRT) said.
