WATERBURY, Conn. -- Waterbury animal control officers said there's no easy explanation for why two sheep have shown up in one of the state's biggest cities this week.

Though there are no farms nearby, a sheep was spotted running down a city street Tuesday. The animal had a tag on its ear, and officials think it may have fallen off a truck passing through the city.Not unaccustomed to housing sheep, animal control officers took the animal to the dog pound and started looking for a home for it.

A second sheep was spotted yesterday in a wooded section of a residential neighborhood. The animal was clearly sick and animal control officers killed it.
