Upon graduating High School, William married his sweetheart and a year and a half later, they had a son. After losing his father on that dark day on 9/11, Billy decided to honor him by becoming a cop. Between the years 2002 and 2003, a serial killer, dubbed MR. HOSTILE, would murder 22 Families, a total of 95 people. Drawn to the case by something he could not quite understand, Altar began having strange insights into the killer's behavior, able to predict his patterns and movements. Altar tracked Mr. Hostile to an apartment building and was ambushed. After a near fatal confrontation, Altar was left to die, but not before Hostile made it clear that Altar's family would pay the price for his "hostility". Altar managed to get himself home but was too late to intervene. When help arrived, they found an unconscious serial killer shot multiple times and an unconscious rookie police officer, near dead. After being rushed to a hospital, Altar lay dead for eight minutes on the operating table. In those minutes, Altar discovered the reality of life after death and touched another universe before being swallowed up and awakening on the operating table, alive. After months of recovery, Altar returned to work at the NYPD and was treated like a hero by his superiors. In order to exploit his media fame for the arrest, he was promoted to Detective and placed in the Special Investigations unit hunting down NY's most notorious and lethal serial killers. He searches, hoping to finally understand his supernatural intuition, and to find answers about his "death".
