Not much is known about Sam, and even the legitimacy of his name is put into question. What is known is that he was chosen by the terrorist cell to be among the first wave of suicide bombers.
Lo-Fi (Part 1)Edit
At the end of "Lo-Fi", he detonates a bomb that he placed under a government-owned SUV.
Mayhem (Part 2)Edit
At the beginning of "Mayhem", it is revealed that the SUV belonged to Hotch and SSA Kate Joyner, who are both investigating the terrorist cell along with the rest of the BAU. Sam approaches a slightly injured, recovering Hotch and asks if he is okay, but the agent doesn't respond. He remained at the scene with Hotch and the severely wounded Joyner until Morgan manages to get past a police barricade, which is set up from fears of an ambush bombing, and tells Sam to leave. Minutes later, Garcia, examining security footage recording the minutes preceding the SUV bombing, realizes that Sam placed and detonated the bomb and alerts Morgan. Morgan pursues Sam to a subway tunnel, where he manages to corner him. However, Sam calmly taunts him and then commits suicide by electrocuting himself on the train tracks. Joyner later dies of her wounds at a hospital.
Sam committed his known attack by placing a bomb under a government-owned SUV and then detonating it when Hotch and Joyner came close.
