Whn he is unable to reach Richard, Pasarian goes to Paul with the news of the murders instead. Paul decides to look into it, and orders Pasarian to examine a fault in the chemical plant's P84 unit the next morning.The morning after, Pasarian examines the chemical plant's P84 unit, but during the examining, the machinery breaks down and refuses to shut off; causing toxic fumes to escape the unit. Pasarian tries to escape the fumes, but dies of chemical poisoning before he can.
