Whoever did this...man... 
The world is full of degenerate, sick, point the finger types. Sick of excuse makers, and low lifes who run amok. Another one on the loose.
When I read the title I thought, you ment "Another nutjob" as suggesting their old goat of a owner wasn't the only one. My bad.
For my two-cents worth, I feel anyone who does kill, should be killed in the same manner(if proven without question). Same thing applies to rape. If someone rapes and is proven to have done it without question, they should have "Bubba" breathing down the back of their neck as punishment. It may not stop crimes like that, but it will make most people think twice about pulling the trigger.
