No. Helps claimed that she was planning to investigate the allegations of assault and harassment, but the letter that she intended to send to the OPCC about the matter was mishandled by her EA and was never sent.
I think you have been duped by a slight of hand as it were.
I think that the letter that would have launched the "planning to investigate" scenario that you are referring to IS the cover letter that she received from their investigator which is the ONLY document that mentions the harassment allegations...that didn't (for some reason) make it's way to Stan's desk.
Sure there was a letter (if it had only been sent to Stan Lowe would have cleared everything up nicely) but it was a letter advising the co-chairs, not a letter of what they were planning to do about it. (it's all in the way an excuse
clarification is worded)
Elsner remained at his post for 6 months after the co-chairs received the cover letter from their investigator that contained the sexual harassment allegations.
That's plenty of time to figure out that the mail didn't get through and that Elsner was still showing up for work in the morning.
