S8, E10: Stabler visits dying lung cancer patient Judson Tierney who's itching to clear his conscience before he goes. Unable to get estranged daughter Sheila to come visit, Benson serves as her replacement as Tierney fesses up to his career in crime before 1971. It was in that year that he murdered his partner and took baby Sheila in to raise as his own to protect her from the hate in that household and give her a better life. However, with an innocent man now imprisoned on murder charges for 35 years, Novak and company fight to get Tierney's confessional testimony into evidence. Tierney helps clear the man's name and catches a momentary glimpse of his daughter before he passes away.
