I'm sure I speak for the vast majority of forum readers here when I express my deepest sympathies for this tragic event. I hope that someone here is able to assist you acquire the information you require to facilitate closure.
That said, I also want to make it clear to the forum users that this is not a thread intended to be a "blame game". It is a fine line to walk between speculative diagnosis and finger-pointing, but we must take care to walk on the right side of it. Comments which stray across the line may need to be removed.
