Ryan Nicholson was 17 when he was fatally shot on October 24, 2015. The shooting happened in the family home in the 5100 block of North Austin Avenue in Jefferson Park, Chicago. Ryan had been in an argument with his older brother Brad Nicholson, 18, after an earlier dispute between Brad and their parents. During a confrontation in the bedroom the brothers shared, Brad retrieved a loaded .45 caliber handgun, pointed it at Ryan, and fired one shot. The bullet passed through Ryan’s left hand and entered his head. Ryan was pronounced dead at Advocate Lutheran General Hospital in Park Ridge early the next morning.

Brad Nicholson was charged with first-degree murder and held on $750,000 bond; he appeared in court on November 13, 2015. The case devastated the family and neighborhood and raised questions about what led to the escalation inside the home. Does anyone have information about the days leading up to October 23 that might help explain how the argument turned deadly?
