Imagine: You had been absent for circa 13 hours for your biiig NON-job in a town far away and you know during circa 13 hours, when you return to your home, it officially has become part of a crime scene, with neighbours, friends, police all over the place AND you will have to answer questions (if possible, facial expression like a severely affected husband) ..........
"Lions?? Cell phone??? Cell phone??? Lions?? Bike??" Nobody had told BM on time, that it would be advisable to ask for his wife perhaps, then storm the house looking for her and signs of her presence/absence and possible explanations to it. (Maybe, True Crime sessions aren't detailed enough for advice.)
What BM mucked out from his home/garage before he drove to Broomfield, was stuff, he didn't want to see/find by neighbours, friends, police. There was A LOT to think about before he started!! Poor felon. What an exhausting Mother's Day it must have been! But yes, nobody said, it would be a (nice) Father's Day.
That BM arranged the "mission of disappearance (murder)" one day before a day of celebration makes me wonder, if he did also with unknown misdeeds.
IMO MOO
