Sergeant Tom Cole was a retired police sergeant and the prime suspect in the rape of Quinn Berris, who he saved from a stalker named Ray Wilson four years ago. After raping Berris, he attempted to frame Wilson for the crime through planted DNA evidence, but SVU detectives saw through this after a lengthy investigation.
Realizing this, Cole kidnapped Berris and took her to his brother's farmhouse in Harding Township, New Jersey. After a standoff at the farmhouse, he was shot to death by Lieutenant Olivia Benson after he attempted to shoot Detective Carisi. Quinn later remarked that she cared for Cole, because he helped, but could not understand Cole's act. (SVU: "Next Chapter")
