A man has pleaded guilty to manslaughter in the 2016 death of Edmonton mixed martial arts fighter Ryan Jimmo.

It's been two years since a Colombian tourist died following what police called an "extremely heinous" attack in northeast Edmonton, and investigators have yet to solve the homicide.

The Alberta Serious Incident Response Team has been called in to investigate a confrontation between members of the Edmonton Police Service and a 20-year-old man, which led to the man being Tasered by police.
