RCMP forensic and tactical units are engaged in the operation, as are police diving teams. The search is focused on Diver Lake, in the city’s northwest, with a secondary search underway at an apartment near the corner of Rosehill Street and Vancouver Avenue. A resident of the apartment building told CTV News he believes the investigation has moved from a missing-person case to a homicide investigation. James Loe says investigators in white coveralls have been combing through a ground-floor unit in the building all morning. On Thursday, police set up tables outside the Regency Manor apartment building and interviewed residents, including Loe, as they came and went from the building.
