"Plane" as in, his biz-jet was tampered with?

If serious, please cite a reputable source for this wild-eyed claim.
Then, explain why the PIC had his unqualified son (175-hr, SEL, PP-certificated) sitting in the right seat instead of the required CE-500-qualified SIC.
If there were any tampering going on, it would be the PIC 'tampering' with the limitations placed on him. (See: John Denver)
I jumped to the conclusion due to another article that mentioned problems finding out what caused the crash. I’ll take down the comment.
