The deputy general manager of the Greater Vancouver Zoo says a three-year-old wolf has been found dead on the side of a nearby road, while a one-year-old female remained missing Thursday. Menita Prasad said both the zoo's perimeter fence and the grey wolf enclosure were deliberately "compromised" early Tuesday, allowing the zoo's nine adult wolves to escape while five cubs stayed inside the enclosure. The zoo in Aldergrove, B.C., has been shut for three days as workers and conservation officers searched for the wolves, of which seven were found, while Langley RCMP investigate the incident as a suspected case of unlawful entry and vandalism.
