Thanks again crush. As usual I get 'access denied' to this link. So I appreciate you letting me know the information contained in the article.
Only a little bit I have to add to your thoughts... I think it's highly unlikely anything placed in a bag would remain in the bag very long once in water. The two items would quickly become separated once the bag was in water.
I don't know whether an extension cord or hanger were involved, those were the shape of marks on her body that the ME said seemed consistent, I think a hairbrush could make the same marks but maybe didn't come to mind for the ME. I have seen several cases where the ME says 'marks consistent with an item such as......', and when a weapon is found, they say 'yes, this could also explain those marks'. I don't see any reason for boyfiend to say a brush in preference to a cord or hanger. It's no better/worse.
Pillowcase, toys and clothes are still a relevant and mysterious aspect of the story I think. I have no idea how, but maybe will come to light as the sickening story unfolds.
God bless you sweet, innocent, trusting Maliyah
