From AARC, of the approx. 30 people I was in group with, Jason Woods and Cody Bates have been arrested for murder and Devon Newson committed suicide in jail. Extrapolating just from my group, graduates have about a 7% chance of murdering someone, and 8-12% chance of attempting or committing suicide in a public enough way to b noticed. And still they claim an 85% "sobriety" rate - sure I guess that works if you're counting dead people and those in high-security lockup as "sober".
Andy Evans also was arrested for murder a few months back - I was not in group with him. Brian Neil (formerly at kids and then staff at AARC) committed suicide a long time ago. That's all I know of for certain, but I know that at least a few more have killed people, and a number have committed suicide.
Keep in mind, less than 400 people have been through AARC altogether.
