I am hoping there is more! If not there is a BIG problem with the legal system.
This is getting pretty scary! Every person with a grandiose persona is going to believe that this is the way to become famous. The media needs to tone down how much they air these violent crimes.
The outcome is the same who ever is to "blame" I am sure that none involved had malicious intent, and all involved and their family and friends are in enough pain without strangers making assumptions and judging.
