Talented golfer, Godly man, friendly guy. Announced a couple weird public lies during high school. Ended up being a murderer.

Some maybe wouldn't consider those weird lies as "red flags", but very strange, especially looking back. Once had a student who attended the school where I taught, though I never taught him personally. He seemed completely normal, he had friends, he was on the golf team, involved in church, had good grades, and I know for a fact he came from a great family. One day he came to a Christian group the school had to speak to some of the younger kids in school. He apparently claimed he had a cocaine addiction, then claimed that jk that was false, then claimed it was real again. I didn't attend but the notion was that it was very awkward and the story seemed very flawed and untrue. Then not too long after he was in our local paper for a story about how a group of kids set his car on fire in the middle of the night and yelled "Jesus freak" as they were running away. Being from a small town in the bible belt, this seemed just out of the ordinary and strange, especially considering his apparent drug addiction testimony before.

Fast forward to his senior year at a Christian college (studying Christian ministries), shot his longtime girlfriend (possibly fiance?) point blank to her head in a car, completely stunned our little town, he's in jail for a long ass time now.
