Right, but this wasn't a poor drug addict with a history of depression (as far as we know), this was the mayor of a town who had been in public office 12 years. Obviously, she could handle everyday "stress." The only situation I would accept of a murder/suicide is if she was extremely "religious" and found out her daughter turned out to be pregnant or something similar to protect their 'reputation.' And even that is pushing it in my opinion.
