It would seem the BBC has a better understanding of why Mr. Johnson chose to do what he did to end Mr Gwatney's life.
He lost his job for writing graffiti on Targets wall.
I personally can't imagine a 50 year old doing that.
But then again maybe he had some help in his erratic frame of mind by a mind altering substance pushed by his friendly neighborhood pharmacist
Perhaps it's time to evaluate just how helpful these drugs really are.
