The City is investigating the unexpected death of a seven year old bull moose at the Chippewa Wildlife Exhibit. The animal died overnight Monday but was discovered by staff early this morning. A vet conducted a post-mortem exam on the moose today, but final results are not yet available. Earlier this summer, a vet determined the moose had worms, a common condition among moose in captivity. The City says the moose was given ample food and water, and was kept cool via shelter and a sprinkler system.
