WINTER HAVEN, Fla. (AP) -- A Polk County sheriff's deputy has died after getting hit by a car while on the job.

Authorities say Sgt. Wes Whitmore had just gotten out of his car at a 7-11 store in Winter Haven when a Cadillac Escalade rammed into his vehicle, pushing it into him and causing it to spin 180 degrees. The Escalade, driven by a 79-year-old man, also struck a business owner and her store -- and continued through a parking lot, shrubs and a retention pond -- before finally coming to a stop. The 60-year-old Whitmore died shortly after. The driver and business owner have been taken to a hospital for non-life-threatening injuries.

Authorities continue to investigate Sunday's crash.
