BBM. I’ve seen multiple comments to the effect of “this wasn’t a hate crime/this had nothing to do with Mallery being queer” in comments sections of prior articles, posted by either the Muenzenberger family or close friends, and that’s telling. Although we likely won’t know what gender(s) she was primarily into we have no idea what DV situation this all stemmed from.
The lack of public photos she had with the woman she was raising Major with at one time is also telling - as is that woman describing herself as “single” online during the duration of the case and her being viewable as a “potential match” for me and multiple other people on lesbian dating apps during that time (disclaimer; Mallery was around my age and her ex girlfriend was local to where I was previously living. The ex looked familiar in the photo CBS posted so I looked through all the people that “liked me” and there she was.)
My theory as of now is that MM started dating someone new that wasn’t involved with CH Jr or his activities on a surface level, but lived/grew up in Madison. Something happens where they leave Madison, with MM and Major possibly already deceased at that point, and they were dumped in Milwaukee, specifically MM in JC’s moms yard. There’s no indication that Mallery was ever in Milwaukee alive at this point.
