I had something like this happen at a small software company I worked about 15 years ago. Our owner had written a specialized program for his wife to sell on the side, but under the company's name. One weekend, after a very big fight, she ended up committing suicide after he'd left the house. The next week, they had me going through her email to get a list of customers she had been working with. I can't begin to tell you the amount of discomfort you feel going through a recently deceased person's email - especially when it was mixed with personal messages. I got in, found all the work related messages, forwarded them to my manager and got out - I couldn't bear to be in there any longer than I had to. No one at the company was very close with her, but it was still a complete shock.
