O’Brien could not say if anyone has been arrested or how Mantee died. The missing person’s case became a homicide several months ago, he said. In late May 2021, about 30 specially trained tactical and forensic identification RCMP officers searched Diver’s Lake in Nanaimo for Mantee and other evidence in the case. An underwater recovery team was in the water while other officers searched the park. Police also searched an apartment at 220 Rosehill Ave. where Mantee lived for a period of time, O’Brien said. “The searches were just part of the evolution of the file. That’s where it really came to a head,” he said.
