Richard Cain (born 1957) is a lawyer hired by "people of means" to defend drug dealer Sally Alvarado from drug possession/distribution charges. Cain and James "Sonny" Crockett butted heads previously, but Cain called him into his office to warn him of his defense strategy--to force Crockett to name his informant, Bob Rickert, in court or go to jail on contempt charges, which is exactly what happened when Crockett refused. Cain dropped his motion when Rickett went to him to admit his involvement in the case.
