OCALA, Fla. (AP) - A veteran Florida Highway Patrol trooper was killed after being struck by a vehicle while she was working a traffic crash on Interstate 75 in Marion County.

Richard and the tow truck driver were pronounced dead at the scene. FHP said the third pedestrian was listed in critical condition at a nearby hospital.

Richard was a nine-year veteran of FHP.
