Specifically, the vet of such films as Black Hawk Down and the award-winning Saving Private Ryan will appear in multiple episodes as a transplanted Detroit Homicide Detective who is now in charge of the Hawaii police department’s Internal Affairs division, EW.com reports. As such, he will be tasked with investigating the messy events of the season finale, including the discovered stolen police money and the governor’s murder (seemingly at McGarrett’s hand).
Sizemore — whose recent TV credits include Starz’s Crash and TNT’s Southland — joins Lost alum Terry O’Quinn as new faces joining the CBS drama for its sophomore run. As TVLine reported last week, O’Quinn will play a Navy SEAL Lt. Commander who trained McGarrett.
