Andrew Daulton Lee

Lee was released on parole in 1998. Kathleen Mills, an activist who had worked towards earning Lee's parole, turned her attention towards the release of Boyce following Lee's freedom and eventually married Boyce. After his release, Lee was briefly hired by Sean Penn to be Penn's personal assistant.

Lee was portrayed by actor Sean Penn in director John Schlesinger's 1985 movie The Falcon and the Snowman, based on the book of the same name by Robert Lindsey. Lee's drug-dealing earned him the nickname "The Snowman," while Boyce's interest in falconry won him his own sobriquet. Boyce was played in the film by actor Timothy Hutton.

In January 1977, Lee (with top secret microfilm in his possession) was arrested by Mexican police in front of the Soviet embassy in Mexico City for littering. Under interrogation he confessed instead to espionage, quickly implicating Boyce in the scheme. Lee was returned to the United States, where he was convicted of espionage. He was sentenced to life in prison and moved to the federal penitentiary in Lompoc, California. Boyce received a sentence of 40 years. Lee's heavier sentence for the same offense was likely due to his prior criminal record and admitted drug trafficking. While imprisoned, Lee lost access to drugs and had no choice but to sober up from his drug addictions. After a period of withdrawal, Lee ended his drug dependency. When Boyce escaped from prison in 1980, Lee was immediately remanded to another facility in Terre Haute, Indiana, a move that caused the end of their friendship.

Andrew Daulton Lee (born 1952) is a former American drug dealer and former agent who was convicted of espionage for his involvement in the spying activities of his childhood friend, Christopher Boyce.
