RE:RE:Possibly I should contact Mark Distler?
Somebody abruptly leaving a company is a human resources issue and the factors behind this are typically protected by confidentiality laws and by company/employee confidentiality agreements. Typically the only time a company will discuss this is if there is some criminal act and the police are potentially involved of which there's no indication here. You can phone the company and ask them all the questions you want but I would be extraordinarily surprised if they have anything to be said beyond what's already been said.
