On March 31, 2016, 37-year-old Virginia State Trooper Chad Phillip Dermyer was killed during an interdiction training exercise at the Greyhound bus terminal in Richmond. Dermyer and about a dozen troopers were taking part in a course when, around 2:45 p.m., he approached a man inside the station. That man, later identified as James Brown III of Aurora, Illinois, produced a handgun and opened fire, striking Dermyer multiple times and wounding two women.

Two nearby troopers returned fire; a short foot pursuit ended inside the terminal and Brown was fatally shot by officers. Dermyer was taken to VCU Medical Center, where he died. Investigators reported Brown had a lengthy violent record and had expressed hostility toward law enforcement; surveillance showed him walking toward his bags before the encounter. Brown was carrying a legally purchased handgun and more than 140 rounds of ammunition. No arrests were made because Brown was killed at the scene.

Did anyone in the Richmond area witness the training that day or have additional details about what happened inside the terminal?
