I believe this particular crash is a 3/10 scenario. The radar track appears to be going straight and level to the destination on IFR flight plan right up until the autopilot disengaged and the pilot couldn't recover. What is notable is the flight path at the time appears to be flying through a frontal boundary with convective weather in progress (storms). The most likely suspicion would then fall to flight conditions deteriorated quickly (or the pilot didn't notice or account for the weather changes he was flying into) and when the autopilot could not keep the plane flying properly on course it disengaged and shortly after shtf for that plane as the pilot failed to recover safely, overspeeded the airframe, and broke up midair.

An anon below posted something about comms. I'm not discounting comms, but I am curious if the Gryder person is Dan Gryder whom has spoken out about things before and been totally wrong (proven in court) with his facts.
