NORTH FORT MYERS, Fla.- Lee County Sheriff's deputies are searching for two vehicles involved in a hit-and-run crash that left a pedestrian seriously injured Wednesday just before 11:15 p.m.

Deputies responded to the crash near the intersection of Pine Island Road and Old US 41. Upon arrival, deputies located 52-year-old Joseph John Kunicki, in the roadway.

Kunicki was unconscious, but breathing, due to being struck by a vehicle that fled the scene. Several witnesses state that two vehicles where traveling together southbound on Old US 41, approaching Pine Island Road.

The first vehicle was a white older model Ford or Mercury. The second vehicle was a blue, potentially Dodge, pick up truck with a white stripe and topper. The white vehicle struck Kunicki, as he was attempting to cross the roadway. Both vehicles then fled the area westbound on Pine Island Road at a high rate of speed.

The white suspect vehicle will have heavy front-end damage to one of its headlight housing areas. Kunicki sustained injuries that were serious and potentially life-threatening.

If anyone has any information on either vehicle, please contact the Lee County Sheriff’s Office Traffic Unit at 239-477-1636.
