A man has been charged with second-degree murder in the weekend death of a welder from Thailand.
Michael John Stewart, 21, also faces additional charges which include one count each of robbery and possession of a weapon.
Another male, Kyle Anthony Brooks, 18, has been charged with one count of robbery and one count of assault. Both are of no fixed address.
Apichat Sudsaneh, 37, was stabbed to death early Sunday morning in front of a house at 80th Avenue and 99th Street while trying to help two friends who police said had been robbed and assaulted by a group of males.
Sudsaneh had been working as a welder in Edmonton for the past two years, and was preparing to return to Thailand this week.
"[Officers] were simply driving north on 96th Street at 107th Avenue when they stopped an individual who was rather boisterous and belligerent towards them. From some keen questioning that they did and pertinent phone calls that they made to our officer, we were able to identify our first suspect," Det. Bill Clark said.
Sudsaneh is Edmonton's eighth homicide victim of 2010.
Police are also seeking two males and three females who they call persons of interest in this incident. They were caught on video at the Health Science LRT station.
