An 18-year-old man and 16-year-old youth have been charged with second-degree murder in the death of Calgary teenager Danillo Canales Glenn.
The 18-year-old died last Tuesday night in the community of Copperfield.
Canales Glenn was playing basketball with friends when he was attacked with pepper spray and stabbed a number of times.
The 16-year-old can't be named due to the provisions of the Youth Criminal Justice Act.
Police aren't releasing the name of the 18-year-old to ensure the identity of the youth is protected.
Police did not disclose the nature of the relationship between the pair.
Each faces a single count of second-degree murder.
Both are scheduled to appear in court Monday.
