Same dog park.
He was a very angry person all the time.
Antivaxxer
Go bag always ready
Anti mosquito fogger thing on his backpack or bag that was always at his side
Always had a gun with him
Repeatedly complained about gays.
I'll never forget the time he was complaining about his son's autism being caused by a childhood vaccine.
I told him the latest studies showed a positive correlation of autism with with maternal use of Tylenol during pregnancy.
He started raging at me and yelling so I left. As I was leaving he walked quickly towards me, yelling. But .. there was a chain link fence between us. His rage, the hatred in his eyes and his words made me think he was going to shoot me.
I have told that story at least 6 times to various people over the years. About a lunatic antivaxxer who I feared wanted to shoot me.
Last time I saw Gerald was about 5 years ago. I'm not at all surprised he murdered someone.
I'm sure there are plenty of people who knew him more recently.
I'm shocked he made thorough 2019-2020 without shooting anybody.
