My wife actually knew the guy from college. They were friends and she said that he was normal then. The last time they talked was back in 2019 when he had went to a baseball game in Florida and my wife wished she was there (we actually made it down there in 2022). The last thing he posted on social media before all of his, um, research was about his mom dying and we wonder if that might have triggered something. My wife was worried about him because he wasn’t getting help and she worried that he would do something crazy, which was a worry that wasn’t unfounded.
