ST. PETERSBURG, Fla. (AP) - St. Petersburg Police are investigating after an officer shot and killed two dogs in an attempt to break up a dog fight.

Officer Slobodan Juric was called about a suspicious person Sunday night. As he questioned neighbors, two dogs on leashes attacked another dog that was not on a leash. Police said the dog owners tried to separate the dogs, but couldn't. Juric fired four times, killing a Rottweiler and a Chesapeake Bay retriever.
