The incident began when in February of 2015, two groups of students began insulting one another on Facebook. Eventually, Powell and his group of friends drove to Yang’s family home to confront Yang and his friends. That confrontation escalated into physical violence, and Powell reportedly fired a BB gun he had brought with him. Yang then emerged from his house with a knife and confronted Powell, resulting in Powell’s fatal injury. Yang was arrested after the altercation and tried as an adult for homicide; Yang was 15 years old at the time.
