Oleg Mickic (Karl Herlinger) was an ex-soldier, and one of the two assassins sent by the Koshka Brotherhood to eliminate Isaak. Mickic had worked for Isaak in the past, and when Isaak discovers that Mickic is being sent to kill him to see if Mickic has any loyalty to his former boss, but Mickic's mind was already made up. Mickic was a sniper who was accustomed to killing from a distance, and had a habit of buying his rifles locally. When Isaak recruited Dexter into helping him dispose of the brotherhood's hitmen, Dexter tracked Mickic to a firing range near the airport where Mickic was testing out his rifle. While Mickic was lying on his stomach for precision, Dexter came behind him and stabbed him through the torso, covering his mouth to muffle any screams. Benjamin Caffrey (Sherman Augustus) was a hitman based in New York and one of the two assassins sent by the Koshka Brotherhood to eliminate Isaak. Caffrey killed all of his victims with from a close range with knives. Caffrey had worked for Isaak in the past, but had no qualms about killing his former boss. When Caffrey was unable to contact Mickic, as he had been killed by Dexter, Caffrey begins to follow Dexter, who Caffrey believed would lead him to Isaak. Caffrey begins trailing Dexter, who leads him to a cargo ship. There, Dexter and Caffrey face off, both wielding knives, but before either can make a move, Isaak appears from behind, shooting Caffrey with a silenced pistol. Dexter and Isaak then threw Caffrey's body overboard. Clint McKay (Jim Beaver) was Hannah McKay's father. A convicted felon and gambler, he initially makes contact with Hannah to reconcile with her about his past behavior. Things turns nasty when Hannah refuses his request for $20,000 to open a business (actually, to pay off his gambling debts), using threats of exposing her for a past murder. He tries to extort money from Dexter as well, so Dexter kills him. Clint's death at the hands of Dexter was a violation of the Code of Harry as Clint had never killed anyone, though Dexter ignored this as he wanted to protect Hannah. Though Clint wasn't Dexter's first innocent victim, he was the first and only innocent victim that Dexter killed in his usual ritualistic fashion, though there were still differences: Clint was still dressed, Dexter killed him directly on
