The incident began when an off-duty FBI agent confronted a motorcyclist accused of reckless driving in the residential neighborhood. The motorcyclist fled but later returned with family members, leading to a traffic stop initiated by Stafford County deputies. The situation escalated when the motorcyclist’s family allegedly refused to comply with deputies’ commands, resulting in a physical confrontation.
Chamberlain, a resident, witnessed the struggle and ran from his yard to aid law enforcement. During the altercation, the off-duty FBI agent discharged his firearm, striking Chamberlain in the chest. Despite immediate life-saving efforts by deputies and Stafford County Fire and Rescue personnel, Chamberlain died at the hospital later that night.
