It's a tragedy and in my experience, people are ALWAYS looking for someone to blame in all tragedy circumstances. I can't believe they are openly blaming him. I would have thought in this situation the blame people felt towards him would have been something they'd keep to themselves as their own suspicions rather than blatantly accuse him. How very sad for him as I'm sure he's already blaming himself in some way. The people who are left behind often have a lot of hindsight is 20/20 issues to battle and don't need additional accusations.
