There are two invisible turkey hunts. On the evening of the 8th when he was standing by the river and sending out all of those friend requests including three guys named Jeff. And early afternoon of the 9th when he was taking down the trail cams all the way over by the RV Park.
You can see why I ended up making the AA easily searchable. Every time you think you've figured out what he was up to, you get whacked with a boomerang from two sections ago.
I've come to think Barry realized exactly who his wife was seeing sometime after getting the "I'm done" text on the 6th. Before that he was suspicious that she was seeing someone, but Suzanne was a champion secret keeper. Somewhere in the fight she must have slipped and he started putting the pieces together and he knew he wasn't going to pacify her this time. Suzanne had a "Jeff" in her past, and Barry knew him:
In the summer after JL’s first year of college in Indiana, he attended a party with some friends at Suzanne’s house. Barry and Suzanne were a couple, but Barry was not at the party. JL said he and Suzanne “kinda hooked up, not really,” at the party. JL played golf almost daily at the time and Barry worked on the golf course.
Barry found out about JL and Suzanne hooking up at the party. Upon seeing JL on the golf course, Barry “jumped off the tractor and he was ready to beat me down.” JL told Barry, “You’re gonna lose your job. You’re gonna lose everything.” JL talked him out of it and that was the last interaction JL had with Barry. (AA)
