Scott Parnell is a minor antagonist in the second season of Law & Order: Organized Crime. He is a member of The Brotherhood, run by Frank Donnelly, and assisted Donnelly in many of his crimes, including robbery, burglary, and assault.
He was portrayed by Patrick Murney.
Parnell first met Detective Elliot Stabler while he was out with the gang for drinks. Stabler played a game where he guessed each gang member's name, including Parnell. After Stabler and Donnelly were called to a crime scene, Parnell met Donnelly there and assisted Donnelly in robbing cash from the crime scene. Donnelly's criminal act was witnessed by Stabler who Donnelly bribed to keep quiet.
Parnell attended all meetings with The Brotherhood and at one point became suspicious of Stabler. At Donnelly's barbecue, Parnell shared to Donnelly that ever since Stabler joined The Brotherhood, police have been suspicious of them. The rest of the gang members except for Donnelly agreed with Parnell's statement. Parnell was also assigned by Donnelly to partner with Carling and surveil Stabler and Donnelly while they robbed a money launderer's house.
Parnell also attended the meeting at the bar where Donnelly announced to The Brotherhood that he will be stepping down as leader of the Brotherhood. When Donnelly announced that Stabler would take over, Parnell became enraged as did the rest of The Brotherhood. After Donnelly found out that Stabler was undercover, Donnelly hired Parnell and Officer Ron Bolton to murder him.
Donnelly told Stabler that they were trying to find a missing Preston Webb to trap him into meeting at a secret location. When Stabler met Donnelly at the location, Parnell and Bolton appeared and attempted to murder Stabler. Parnell then ended up shooting Stabler three times after he jumped out a window but luckily for Stabler, he was wearing a bulletproof vest. Stabler then tracked down Parnell and Bolton and assaulted both before handcuffing them to poles. Parnell was then arrested by Bell and the task force for assisting Donnelly in his crimes.
