Authorities say a central Florida sheriff's deputy has been struck and killed by a car that continued on a destructive path, hitting a businesswoman and her store.

Authorities say Polk County Sgt. Wes Whitmore had just gotten out of his car at a 7-11 store Sunday 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, continuing 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.
