ASHEBORO — The only grizzly bear at the N.C. Zoo died Friday. Tommo, a bear relocated from Yellowstone National Park, lived at the Zoo for 26 years. The zoo’s staff made the decision to euthanize the 31-year old bear after his quality of life quickly declined. Tommo arrived at the Zoo in 1995 after being identified as a “nuisance bear” — a bear who has lost his fear of humans because they see people as suppliers of food. The grizzly bear habitat at the zoo will remain empty while the staff works with other agencies to offer a home for any orphaned or nuisance bears in the future.
