I read them too and from what I gather he was involved in a hit and run which killed a motorcyclist. My guess is he ran because he was drinking
Judging from the comments on the news article that shows his picture and lists his name, the guy he killed had LOTS of friends and many of them Harley folks. I'm not sure if its gang affiliated bikers, but not a stretch.....
I'm pretty sure he and his family were being harassed by people angry that he left the scene and left the guy to die. I don't think he was hallucinating anything at all. I see it happening very easily.
