However, while Dexter was rescued and adopted by Harry Morgan, Brian was left behind and sent to a mental institution due to his severe trauma.

As an adult, Brian reinvents himself and becomes the Ice Truck Killer, a meticulous and sadistic serial killer who taunts the Miami Metro Police. His murders are deeply personal, as they serve as messages meant for Dexter.
