What blanks are you referring to?
After the internal investigation cleared Horner of any wrong doing (Wed 28th Feb), the press said they spoke to a source who is close to the accuser saying the female employee is very unhappy and that the investigation was very one side and that she has been 'crucified' by the investigation. (source

Then a couple of days later (somewhere around 3rd-5th March but most articles appearing on the 5th March) Geri Horner (Horner's wife) is claimed to have allegedly told her husband that he is to have no contact with his accuser (source:

Then 2 days later (7th March) the female employee is suspended.
So the time line
28th Feb - Horner is cleared of any wrong doing
3rd - 5th March - Horner's wife allegedly tells him he is to have no contact with the female employee
7th March - Female employee is suspended.
It does not take a rocket scientist to see what is going on with that time line. Gerri Horner is a very influential woman in her own right being a member of the all female music group the Spice Girls. 2 Days after her alleged request of her husband, the female employee is suddenly suspended.
As for the comment about the importance of Horner, history is inundated with news articles of high value politicians, high value celebrities, high value sports people all doing wrong but have been cleared of any wrong doing because of their high status and their importance to their job and the people around them. Why can it not be the same for Horner? He has been extremely influential in the success and continued success of RBR. Do you honestly think RBR was going to find Horny guilty of wrong doing? knowing that if they found him guilty he would probably not be able to work at RBR again and thus RBR's dominance in F1 be put at jeopardy. Millions if not billions of $$$ or £££ would be at stake on the outcome of the investigation.
Horner is well known in the industry for being a hard task master with the question being did he take it a bit too far and now Red Bull is doing all it can to protect him because to lose him could cost Reb Bull billions in $$$/£££. No way are they about to let such a thing happen.
