A man has been charged in connection with a Calgary sexual assault police say happened 20 years ago. According to police, the suspect was 14 at the time and cannot be named under the Youth Criminal Justice Act. But on Monday, they said he’d been charged with a single count of aggravated sexual assault. The incident he’s believed to have committed occurred around 4:30 a.m. on Aug. 6, 2006, in the 500 block of 47 Street S.E. Police say a woman, 18, was walking through a school field when she “was sexually assaulted and stabbed multiple times.” A DNA profile was collected in the aftermath and entered into the national data bank. This past Sept. 21, police say investigators were alerted to a DNA match. Staff Sgt. Tom Hanson says the local force will “never stop pursuing answers for victims of sexual assault, no matter how much time has passed.” “This case was moved forward by the persistence of many investigators, from those who began the investigation in 2006 to those who saw it through to a charge,” Hanson said. “Unsolved doesn’t mean forgotten.”
