My theory, for @ZellnerCrimeLaw: TH left ASY, went back to photo Zips, then drove home (“all roads lead to one door”) with updated planner page & AT paperwork. Changed into cowgirl costume for H’ween party (RH told reporter TH wearing costume last time he saw her - WHERE is it?)
RH was there “dropping off” stuff to SB. MH, too (“grieving process” before RAV found). TH threatened to expose drug biz operating in her home. RH freaked & killed her. Called MW & KK directly instead of 911 to avoid home investigation that could get them all in trouble.
