So the 430pm ish ride would be out of character? It would make more sense to panic if she was presumed to go on her normal ride and then never showed up for church. The panic at 6:30pm seems to be missing key information or it's nonsensical.
Did she make it to church that day? I'm not sure if churches were open in CO or what the orders were for the state or her preference. It also bothered me that it was even considered that a voluntary firefighter training would be scheduled on mother's day. For the lucky FF that have mothers day off, nearly all have a mom, are a wife or a mom themselves, and might have both they want to celebrate. Wives of FF are already asked to sacrifice a lot and adding mothers day would be insensitive and not conducive to promoting "family culture" within the department and at home. I know the Fire Chief said something like "not that he knows of" or essentially not part of what he would have sent him to.
Then I think he was out of town working on Mothers day? I mean I guess. I still don't know who last saw her alive or when that was. That should be easy enough information to figure out.
Churches were
not open and the particular church that Suzanne attended had gone online weeks before. It was online that day (at 9 am, IIRC).
I'm sure LE knows something about who saw her last, although they would have to check every word out of a particular person's mouth since that person has already changed their alibi story one time.
I don't think the panic began at 6:30. I think family tried to contact Suzanne earlier on Mother's Day, tried again mid-day, became concerned, tried again late afternoon (whereupon the neighbor went to the house - which took several minutes - probably up to half an hour, get ready, walk over, look around, apparently see that the car was there, see that Suzanne was not there, glance up and down the driveway, maybe check for bike, then head back to the house to report to whoever they were talking to in the first place - seems to be the daughters).
Then the daughters confer with each other and call the neighbor back. I see that rising panic as taking about an hour, and I suspect conversations took place before the 911 call was made at 5:45 pm or thereabouts. I'm guessing a flurry of phone calls between various parties began around 4-4:30 after rising concern about missed phone calls (say...one at 11 am, another at 3 pm). If BM told everyone the same thing he's said elsewhere (that he was home on Sunday morning and asked Suzanne if he could go to Denver), and if he assured the girls that their mom was just on a bike ride in the morning, they wouldn't start to panic until the afternoon (which is what I think happened).
BM says he was in Denver. First he said he had fire training that day (and the nephew, I believe, announced that to the world). Then Fire Chief said there was no such training. So then BM says it was work related (went to Denver to prep a job site).
LE has not verified either of these stories, but the Fire Chief pretty much flattened BM's first alibi. The second is easily verified, I would think. I have a strong feeling (as I always do with second alibis) that it too is a lie.
