Johnny Lewis killed his landlady and her cat and ultimately fell to his death in her driveway. At the time the Sons of Anarchy actor died, everyone assumed he was on drugs and had come from rehab not long before and even his attorney suspected Johnny was on drugs. How else do explain what he did that day? Yes, he had been suffering from mental issues, but everyone thought it was drugs. In a report released yesterday though, the coroner said there were no traces of any drugs or medication in his system.
