Tyree Cayer, 28, was a former star running back with the Elmwood Giants, helping lead the high school football team to the 2011 A Division championship game, where the Giants lost to the Sisler Spartans. “You always had the biggest smile on your face and gave the same smile to everyone around you. Rest in peace bro!” said a post on Cayer’s Facebook page. “The halls of Elmwood are very sad today. May peace find you all at this difficult time,” said a post on a Facebook page set up in Cayer’s memory. Tyree shares a moment with his aunt Chantelle, who passed away in 2017. Cayer’s mom, Tania, said the two were best friends. (Submitted by Tania Cayer) Three boys aged 14 to 16 now face charges in Cayer’s stabbing death. A 15-year-old and a 16-year-old are charged with manslaughter, while a 14-year-old is charged with second-degree murder, police said in a news release Tuesday. More arrests are expected as the investigation continues, police said. The boys and Kayer got into a verbal argument Sunday afternoon that escalated into physical violence, police said. Kayer was then stabbed by one of the boys. Officers were called to the library, at Donald Street and Graham Avenue, just after 4:30 p.m. Cayer was rushed to the hospital in critical condition, where he was pronounced dead. A number of police vehicles sit outside the Millennium Library at 8pm on Sunday, three and a half hours after police were called to the stabbing. (Donna Lee/CBC) The three boys fled before police arrived, but homicide investigators identified them, according to a police news release. Cayer’s mom, Tania, sent an email to CBC News, urging people to remember him as Tyree, not Winnipeg’s 51st homicide victim of the year. “I am proud to say he is my son,” she wrote. The library will remain closed until at least Dec. 19 “as we evaluate next steps to ensure the safety of all staff and visitors,” the City of Winnipeg said in a statement. Anyone with information that could help investigators is asked to call police at 204-986-6508 or leave an anonymous tip with Crime Stoppers at 204-786-TIPS (8477).
