JACKSONVILLE, Fla. (AP) - A robbery suspect was shot and killed during a gunbattle that also claimed the life of a police dog.

Police say the suspect stole a car in a dollar store parking lot and evaded police for a half hour Monday night before crashing the vehicle. The suspect ran as a police helicopter tracked him. The K9, named Sarge, was let off the leash to pinpoint the suspect's location.

That's when shots were fired. Police say they aren't sure if the suspect shot Sarge or if the dog was caught in the gunfire exchange.

Jacksonville Police Chief John Hartley credited Sarge for keeping the officers safe.

The suspect's name has not been released. Police continue to look for a second suspect.

Three officers were placed on administrative leave pending an internal investigation.
