The Command Center bombing was a catastrophic attack on the FBI Command Center in New York by former FBI recruit, Elias Harper during the last day of the 2016 Democratic National Convention. The event occurred three days after the Grand Central bombing. The bombing killed 32 people. Simon Asher was initially considered the main suspect of the bombing but later, pardoned and brought as a witness to testify against Elias Harper in the FBI Congressional Hearing, three months after the attack. Later, it was revealed that Liam O'Connor was the mastermind behind the two bombing attacks. Liam planted the bombs at Grand Central Terminal using the bombing plans from Simon Asher in the past timeline at Quantico and blackmailed Elias into capturing Alex Parrish and framing her as the suspect of the Grand Central bombing case. In addition, he blackmailed Elias into capturing Simon by planting the bombs at the Command Center. In order to frame him for the bombing, Elias strapped Simon to a chair with a bomb trigger on his hand, leading Alex and her colleagues to believe that he was the main culprit behind the attack.
