“At this time, we’re still investigating. We do have three vehicles that remained on scene, but we do believe she was struck by several other vehicles also. At this time, we don’t have a description of those vehicles. Once we speak to witnesses and the other drivers, we hope to get a little more information on the other vehicles,” said Sgt. Wysocky.

The westbound lanes were closed for hours during the accident investigation with traffic detoured to State Road 84 near the Davie Road exit and then back onto westbound I-595, he said.
