This may sound trite, but re the BBC issue - one thing I have learned as a lawyer involved in many cases of messy human situations is that you rarely know and can pretty much never predict what is happening until you actually *know*, i.e. you see detailed accounts from the individuals involved and documentary evidence.
And in pretty much 100% of situations, the truth is unexpected, often stranger than you anticipated - and invariably exposes the expectations you have (without realising it) wrongly placed onto the situation, sometimes based on your own prejudices.
Also, family situations can be so complex and difficult.
So, whilst it is important that the BBC are held up to scrutiny, there is clearly at least one potentially very vulnerable individual involved, and a large dollop of social media/press-driven 'we must know NOW and SOMEBODY must be to BLAME', and the truth will probably end up being more complicated and difficult than people want it to be.
