Nothing in TFA or the NBC article linked by TFA provides enough information to conclude reckless homicide. All that is confirmed is a car leaving a roadway, crashing, and catching fire. What's your source for concluding reckless homicide?
Video of the crash as he was stunting for the camera and killed himself and his passenger in the process.

None of the reporting even specifies who was driving.
There is video of the accident floating around. I recommend against going looking for it...
