No-one is saying the investigation didn't have anything to do with her tragic death. Any partner/spouse of someone having to go through any Court for any criminal behaviour will tell you how stressful it is. In this case however, it does seem clear that Mrs Paterson was not a silent and totally innocent bystander, and that some of the payments for lobbying were through her own contacts via her own position.
Tragic it certainly was, but you can't stop investigations because of the stress it causes to the accused or his/her family.
