“RCMP weren’t allowed to tell me, I asked” was what he said when asked about the result of Maleyah’s polygraph. I believe you misheard. It would be easy to mishear “she didn’t tell me” I had to replay it to myself 3 times to be sure.I didn't realize Mom had also taken a lie detector test. He said she 'didn't want to tell' him the results. So, apparently they have had contact since she's been living somewhere else.
The question about Maleyah’s polygraph begins at about 4:40 in the video.
