Prosecutors have decided not to charge former Commerce Secretary John Bryson, who resigned on June 21 after he was involved in a series of bizarre car crashes. Prosecutors made the decision after reviewing a felony hit-and-run citation that police filed Monday. Concluding an investigation, detectives decided there was evidence of a hit-and-run, though no details were released. Bryson was found unconscious in his car, apparently having suffered a seizure while driving. While Ambien was found in his system, there was no evidence that the drug played a role in the collisions. Authorities said he hit one car, drove off, and then hit another before he was found.
