Almost like, it wasn't happening at all, isn't it. If there was such a letter sent to the police in 2018 - they would have investigated it, if he was guilty it would have been known by everyone by now. But the fact is we have MM word that the police received a random letter (one of thousands if it existed at all), and now it's only known because her brother announce some accusations to the world, for which he was paid.
What we need is for the police to refute or not what she said. And if they did indeed receive such a letter, what happened next? Are they liable for doing nothing about alleged child abuse or is it made up, like the we got married before the wedding / the rf is racist crap.
I do not believe this MM bs for one minute. It's a convenient story for her to justify her actions (and for her brother to make money from his dad after his dad stopped funding his lifestyle).
They are desperate remember. Absolutely desperate.
