The day before the wreck, Barnes was convicted in an Upper Keys court of DUI with a prior and driving with a suspended license, said Monroe County Assistant State Attorney Colleen Dunne. Barnes was ordered to impound her car, and her driver's license was revoked for five years, after which time she must have a Breathalyzer ignition interlock device on any vehicle she drives, Dunne said.

Barnes and Charles Judy were southbound in her Thunderbird at 11 a.m. when they slammed into the back of a 2006 Chevrolet pickup driven by David Schoff of Palm Bay.

Barnes allegedly drove another half-mile, then switched seats with Judy, who allegedly claimed to be driving, Annunziato said.

"She jumps in the back seat and he moves over," Dunick said. "It was like the old comedy bit, 'Who's on first?' "

Burns on Judy's chest from the passenger-side airbag deploying belied their story, Dunick said. The airbag in the steering wheel did not deploy, he said.

Troopers charged Barnes with driving with a revoked license, reckless driving, leaving the scene of a wreck with injuries and driving with no insurance. Judy was not charged.

Barnes faces a maximum of a year in jail if found guilty of violating her probation due to the wreck, Dunne said.
