In Washington, a 15-year-old boy has been charged with murdering his parents and three siblings. His surviving 11-year-old sister provided critical insights into the attack, detailing gunshots, injuries, and the alleged actions of her brother. Following the attack, the boy staged the scene blaming another sibling and called 911, falsely claiming that his deceased brother was the shooter. Authorities have classified the incident as a systematic murder. A court hearing is scheduled to determine if he will be tried as an adult, which could lead to significant prison time.
