Mulwray

Mulwray was an employee of the Butler Institute at their New York City offices. He at first worked in the Biostock Acquisitions department, but when he was caught attempting to hack into the company's computer system, his boss, Mathew O'Hara, was impressed with him and let him in on his plan to save humanity from the collapse of Earth's environment by having copies of their minds uploaded into computers.

On his last day in Bio, he and his partner Lewis Christian shot James McIlveen and acquired his body for research. He later caught Stephanie attempting to hack into the company's computer system and took her to O'Hara, who instead let her in on the plan as well. Mulwray, who hadn't taken O'Hara's claims seriously, was shocked to learn that his young son Patrick O'Hara had volunteered to be a test subject for the procedure. He became increasingly distraught, and eventually tried to shoot O'Hara; however, Stephanie had already alerted O'Hara about Mulwray's emotional state, and had the firing pin removed from his gun as a precaution. O'Hara then shot and killed him instead. (NA: Cat's Cradle: Warhead)
