Ben Abner

Ben Abner was a terrorist and member of a terrorist cell, who appeared in Mayhem.

History
Not much is known about Abner, and even the legitimacy of his name is put into question. He first appears in "Mayhem" when he drives his ambulance past a police barricade that was set up in fears of an ambush bombing and arrived at the scene of an SUV bombing that injured Hotch and severely wounded SSA Kate Joyner, both of whom were investigating the terrorist cell along with the rest of the BAU. Abner takes them to a nearby hospital, which is currently closed off by Secret Service agents guarding an unnamed government official that is being targeted by the cell. Hotch convinces the agents to let the ambulance enter, and doctors attend to Joyner while Abner goes missing. The rest of the BAU arrive at the hospital and eventually deduce the cell's real target, as well as Abner being the one responsible to detonate a bomb in the hospital. Abner goes to the garage with the bomb, killing four Secret Service agents along the way, and loads the bomb into his ambulance. Morgan, however, manages to steal the ambulance and drive away from the hospital. Distraught at his failure, Abner detonates the bomb anyway, but Morgan is able to jump out of the ambulance after taking it into an empty area. Immediately after, Abner commits suicide by slashing his throat with a knife.

Modus Operandi
During Abner's known killings, he repeatedly shot his victims, four Secret Service agents, with a handgun. He then attempted to detonate a bomb loaded inside an ambulance vehicle, but the attack failed.
