The investigation into a crash that killed a prosecutor is finished.
Versailles Police told the Lexington Herald-Leader that they have closed their investigation into the death of Fayette County prosecutor Brian Mattone.
On May 2, Mattone's SUV ran off Old Frankfort Pike, hit a tree and fence and burst into flames.
They say toxicology reports show he had not used drugs or alcohol before the crash.
Police say they'll probably never know what caused the wreck.
