Paul Michael Sandig was a wealthy businessman and the prime suspect in the murder of Detective Robert Croft. He laundered $6,000,000 for drug dealer Ted Quinlan, while making almost $1,000,000 cut of the profits. Croft was undercover as "Bobby Cassidy" during Quinlan's laundering scheme. When Sandig found out Croft was onto him, he shot and killed the detective to silence him. Jack McCoy gave Quinlan immunity for his testimony against Sandig, which reinstated the capital charge. Sandig was tried and convicted of murder in the first degree and unanimously sentenced to death.
