His best friend, Zabbie Safari, told CBC News that Yar was well-liked and loved to make people laugh."He was a beloved son, a loyal brother, he will be missed by everyone," said Yar's father Ismail during Thursday's press conference. "He took all our joys with him and our home and hearts are empty without him."Yar's sister Aasma said she still can't make sense of what happened."I'm used to him being so loud and so goofy … a heart like that is very rare," Aasma said. "It doesn't feel real that I'm looking down at the grave of my 15-year-old brother."Police are still looking to contact a number of people in a Chevrolet Tahoe seen at a residence in the Saddleridge area before and after the event."These people are believed to have knowledge of the incident," Chisholm said. "The actions that night have led to tragic consequences and we remain committed to uncovering how this all came to be."Anyone with information is asked to contact police at 403-266-1234 or through Crime Stoppers.
