I wonder if that's the previously mentioned Florida trip where Suzanne wanted or planned to go by herself, but Barry showed up.
So, in summer 2018, Barry signs up for volunteer firefighter training (probably level 1) in Salida. By November, they have purchased the Puma Path house, IIRC, without a bank loan (but we don't know if paper was taken back by the prior owner or if Barry knew the owners). Then we have the Christmas photo from 2019, I believe it was (it's Christmas morning, according to Suzanne's FB, the one where Barry is reading the Bible). So perhaps Suzanne wanted a kind of family reunion before she moved "out west." FL would be a good place for everyone to meet up.
I believe the road trip to visit the colleges (Barry and elder daughter, posted on Suzanne's FB, posted here as well), was Spring 2018. I'm just trying to piece together when Suzanne may have first gone to CO - did she go househunting when they bought the house in November? Or did she just look at pictures? MM says Suzanne liked the house - but we can't know for sure if that was "in love with the house" or "in love with the house Barry wanted." Many a person has fake-liked something in order to placate an ornery or abusive spouse.
Barry claims it had been 3 years since she was estranged from her family (so from early-mid 2017). Why would she be avoiding her family even before the move and even before the loan that Gene graciously gave them? Clearly, they were in touch with her family when the loan was made (and according to the siblings, afterwards, although there may have been some squabbling...)
Now we know that she reached out to her father just a month before her disappearance, and that she corresponded with Andy on her birthday - just days before she went missing. Was this renewed interest in her own family and this reaching out...uncomfortable for Barry?
Maybe he's a grudge collector.
Or someone who is really bad with estimating time. Or is motivated to estimate time in order to support his own grandiosity. By this, I mean, it's *his* calendar that counts as history and he is accustomed to restaging the past. Again, I know this sounds really familiar to a lot of you.
I mean, he did eventually put the long gun down and let Andy come on his property to look around. Not exactly to "look for Suzanne," but I bet that's what Barry's timeline says.
