Andrew Daulton Lee (born 1952) is an American drug dealer and former agent who was convicted of espionage for his involvement in the spying activities of his childhood friend, Christopher Boyce.
Lee was the adopted eldest son of Dr. Daulton Lee, a wealthy California physician. His lifelong friendship with Boyce led him into espionage activities after Boyce, a code clerk employed with the large US defense contractor, TRW (headquartered in the Los Angeles community of Redondo Beach), began stealing classified documents detailing how to decrypt secure US government message traffic and detailed specifications of the latest US spy satellites with the intention of delivering them to agents of the Soviet Union. With Boyce's stolen documents, Lee traveled to Mexico City, where he delivered them to Soviet embassy officials. Lee often also would use these trips as an opportunity to engage in drug deals when not working on espionage. A common tactic of Lee's drug smuggling was to learn of airline routes, where he would fly from Mexico to the United States, hiding the drugs inside a compartment of the plane (mainly the airline restroom), purchasing a ticket to whichever destination the same airplane was scheduled, then recapturing the drug stash after disembarking at the new destination.
Lee and Boyce made an agreement to evenly split the profits from the espionage ring. Boyce had used his share mainly for his personal use. Lee used his split of the profits to further his drug business, purchasing more expensive drugs, such as heroin, and being able to gain tremendous profits by selling the expensive, hard-to-obtain drugs in the United States. At one meeting with his Soviet handlers, Lee proposed that they assist him in his drug trade by transporting cocaine from Peru to the Soviet embassy in Mexico under diplomatic seal. At points when Boyce was doubting the effectiveness of his espionage, Lee had convinced him that the spy ring should expand. Lee had proposed adding his younger brother as an alternate courier, as well as recruiting a friend who was a US Navy sailor aboard an aircraft carrier, and having a fellow drug dealer be brought into the spy ring to sell the same intelligence reports to other foreign nations, namely China. Lee did indeed (behind Boyce's back) make copies of the reports with the intention of selling them to the Chinese.
