I'm looking for a movie. Please help

Good morning,
I'm looking for a movie - I remember a bit of the plot.
This film is about a son who returns from prison or juvenile detention to his mother and younger brother. Their mother raised them without a father. The older brother is a bad influence on the younger one. I remember a scene where they ran out of fuel and the elder went to the station with a canister. He came back very quickly. The next day it turned out that someone had been attacked on a nearby road. The younger son and others suspect the older one. Unfortunately, I don't remember how the movie ended. The film is set in a desert, very dry territory of the USA. The film was probably made around 2005 at the latest.
Thanks for the reply from the answer.
