Gerald Leighton was the leader of the gang involved in the hostage situation at the Sanderson Corporation and the palladium heist in a nearby building.
The Police Department believed that a Lucas Vincent was behind the hostage situation at the Sanderson Corporation. During the investigation it was revealed that a Face Maker was used by the gang to disguise themselves as members of the Holy Reclamation Army to throw off the investigation into the true crime actually taking place, a palladium heist. Gerald Leighton was using the Face Maker to disguise himself as Lucas Vincent.
Leighton was linked to four high value robberies in the past two years. From his actions during his final heist, he had few morals and no problem with murdering hostages, seeing them as little more than collateral to use against the police.
