Absolutely nothing is known about Johnson, other than he became an anarchist and a neo-Nazi at some point. He later became a follower of Eric Rawdon, a fellow anarchist who plotted a terrorist attack against the U.S. When Rawdon was convicted of burglary, breaking and entering, and criminal conspiracy and imprisoned at Virginia Supermax Prison, Johnson and Rawdon's other followers began planning to break him out of prison.
After the anarchists frame Aaron Hotchner, who profiled Rawdon, for conspiracy, Johnson and two other anarchists break Rawdon out of his cell along with numerous other inmates by killing the prison guards and taking over the control room. When Captain Grant Howard and a SWAT team enter the control room, Johnson, posing as a guard taken hostage, shoots Howard, and his accomplices kill the other SWAT agents. When Rawdon enters the control room, he orders Johnson to release the serial killers contained in the prison's serial killer wing to murder Lewis, who is guarding a potential escape route. While doing so, Rawdon orders Johnson and the other anarchists to disguise themselves as SWAT agents and guards by stealing their clothes and guns. Afterwards, they go to another cell block, where they find Reid, JJ, and a SWAT agent. They shoot the SWAT agent and then engage in a gunfight with Reid and JJ. Moments later, Hotch and more SWAT agents arrive. Hotch shoots and incapacitates Rawdon, causing him to drop a flashbang grenade that incapacitates him, Johnson, and the other anarchists, allowing the SWAT agents to make the arrests.
During the Virginia Supermax Prison break and attack, Johnson shot Captain Grant Howard in the neck with a handgun. Then, he used a stolen assault rifle to kill a SWAT agent and shoot at Reid and JJ. He also set loose a number of serial killers to kill Lewis under Rawdon's orders.
No official profile of Johnson was made by the BAU, as they were more focused on Rawdon.
