I never understood the term "untargeted hit". Can someone explain? When I hear "hit", I think murder for hire. That, in my mind, means there must be a target. (Sorry if this has been asked and answered before.)
IMHO, LE and family believe Missy was targeted. LE's later statement that they no longer believed she was targeted due to a love triangle and that they are now looking into the possibility that she was not targeted says to me that theory #1 (related to outside relationships) didn't pan out and now they are exploring other avenues - as they should. They could be exploring a host of other theories. Until/if this case is solved, new leads very well could lead them back to theory 1 (or any other theory, or a previously unconsidered theory.
IMHO, nothing is off the table yet.
