This guy I knew in high school, he would hang out with us sometimes, had a couple of friends over at his house one afternoon just sitting around smoking weed. He got out his grandpa's sawed off shotgun and it accidentally went off while he was fucking around and he killed a girl. He got convicted as an adult with murder 2 because it was an illegal firearm. Served 15 or 16 years I think.
A couple of years ago, another guy I knew growing up committed suicide by cop. I don't know how it all went down but somehow he ended up in a standoff on a county road surrounded by LEO. He was standing in the road with his bow (yeah I dunno, but Guy was standing there with his hunting bow) and he drew an arrow and took aim at one of them.
My brother in law's brother was shot and killed by his next door neighbor a few years ago, just before Christmas. From what I know they had a longstanding feud with multiple ongoing arguments and a few fistfights, lots of intervention from law enforcement. The night it happened the neighbor came over and was yelling at our man from the front yard. Brother went outside to run him off and was shot dead right there. His wife had started videoing it when the neighbor first showed up because of the history and was about to call the cops on the neighbor again, it was all on her video.
Last week on Christmas Eve, (from the same sister and brother-in-law) my nephew's girlfriend's brother was murdered by some guy that told the cops he "just wanted to see someone die." That guy killed two people that night.
