Hi Annandale,
First of all, I am so sorry for your brother. That has to be hard. Janet was a very kind and genuine person. That is why this is so sad. That and the fact that Kaiden is without a mother. The hardest thing is that so far nothing has surfaced that takes the focus off of Raven. At the very least, Raven was a VERY BAD husband.
In regards to the memorial service in Annandale, yes, he was there the whole time. After the actual service ended, the families went into the back. Raven's family was in one room and Janet's was in the other. Raven only came into the room with Janet's family once, and it was for a brief moment, to show the video. After that he left. The two families did not interact. So, it is possible that if folks were in the back room with Janet's family after the service, they would not have seen him.
Hope this helps...
Take care,
Moxie
