COLLIER COUNTY, Fla.- Florida Highway Patrol is investigating a single-vehicle crash that left 22-year-old Dylan Tewis in critical condition Tuesday morning. Officers say it happened on Logan Rd. N. at Cove Cir. at 4:15 a.m.

Tewis veered off the roadway for unknown reasons, and his Jeep Liberty flipped multiple times before landing on its wheels.

FHP says alcohol was not a factor, and Tewis was wearing his seatbelt at the time of the crash.

No charges were filed against him.
