[TOMT] Movie stuck in my head for years maybe based on a true event, need help!
hope I tagged that title right, I'm new here.
This one is probably going to be tough, Chatgpt did its best, but ultimately was no help, this is a movie that's been stuck in my head for some time, and I remember only bits and pieces, but here's the most accurate keyword summary I can give, if you ask I might be able to remember some other details, but very few, I only mostly remember the murder, and even that is spotty in my mind, I believe this was a 90s indie FIM, or low budget, but it seemed pretty realistic, at least at the time, and too specific it not be based on a true story, or true murder.
Three teen boys drive a trusting friend in a (black van?) to a desert/sandstone rock formation. Hidden MAC-10 style guns are retrieved from the rocks and the friend is suddenly executed. The killers were joking beforehand and stood in shock afterward. Low-budget realistic movie seen on YouTube around 2009, possibly based on a true story.
Fingers crossed 🤞
