Christopher Crim, a 24-year-old from Festus, Missouri, was fatally shot on June 6, 2015, outside a trailer home on Cankelly Lane in Caseyville, Illinois. Around 2:00 AM Crim and two companions, John Fox, 25, and Anthony Pentecost, 22, drove about 50 miles to confront Crim’s ex-girlfriend and her new boyfriend, Dustin Prestito, 23. The trio attacked the ex-girlfriend as she was leaving the trailer, with Pentecost striking her and the men damaging her car.

The men forced their way into the trailer and confronted Prestito, waking his brother, who armed himself. After a warning shot the fight moved outside; Fox and Pentecost returned toward their vehicle while Crim picked up a blunt object and threatened to beat Prestito and his brother. Prestito’s brother then fired, striking Crim, who was found next to the house and later pronounced dead at the hospital. Investigators determined the shooting was an act of self-defense and no charges were filed against Prestito’s brother. Fox and Pentecost were arrested on felony home invasion and mob action charges; Pentecost also faced a misdemeanor battery charge, with bail set at $60,000 for each.

Are there details from the scene or witnesses that could shed more light on how events escalated that night?
