Former FBI Director Louis Freeh likely dozed off at the wheel and drifted off the roadway before an Aug. 25 single-car crash that left him seriously injured, Vermont State Police said Wednesday. Investigators previously said there were no drugs or alcohol involved, and they have now confirmed that there was no mechanical problem. "Mr. Freeh was interviewed and does not remember how the crash occurred. A lack of memory is common in crashes of this nature," the state police said in a statement. No charges will be filed against Freeh, who broke his leg and was banged-up when he drove into a mailbox.
