Calgary police say a male suspect was arrested Thursday, the culmination of an investigation that began when Crouse disappeared after leaving a party in Abbeydale, Alta. Weeks later, his body was found in a retention pond near Stoney Trail and 16th Avenue NE “Since 2014, homicide detectives have conducted extensive witness interviews and scoured CCTV to identify a suspect. Recently, members of the public came forward with new evidence which allowed us to take the investigation forward,” police said in a statement. The suspect arrested Thursday has not been named, but authorities say he and Crowshoe were known to each other and had attended the party together. Police say the pair left the party together and, at some point, an argument ensued that led to Crowshoe’s death, with his body dumped in the lake. A motive has not been determined, but there are not believed to be any other suspects. “Our homicide detectives have been incredibly tenacious throughout this investigation,” said Staff Sgt. Sean Gregson of the Calgary Police Homicide Unit. “Homicide investigations require support from resources across the agency, and for eight years our CPS investigators have worked tirelessly to find answers for Colton’s family.” The identity of the accused will be released once charges are formally laid.
