I had a great aunt that died by electrocution in the bathtub. It was determined to be an accident but the family have always wondered if there was more to it. Some think that her husband had something to do with it but it couldn't be proven. This was many many years ago. The family didn't put a front up about it, they just didn't talk about it.
But yes, there are families who do put up a front because they want or need to maintain a certain image. If the story doesn't add up then it's probably not true.
