An animal control officer shot and killed a pet dog in a Massachusetts town after mistaking it for a coyote in an incident local police are describing as a sad mix-up. Police in Northbridge, Massachusetts, say the shooting happened on Tuesday after police received a call of a report of a coyote in a residential backyard. Police say the animal control officer went into the woods to look for the coyote and found what they thought was the animal in a threatening position and shot it. The incident happened as communities around Massachusetts and the country have dealt with an uptick in interactions between coyotes and people.
