exposed after Lee was arrested by Mexican police in front of the Soviet embassy on 6 January 1977. His arrest was "almost by accident": Lee was arrested for littering. During his harsh interrogation, Lee, who had top secret microfilm in his possession when arrested, confessed to being a Soviet spy and implicated Boyce. Boyce was arrested ten days later on 16 January, when the FBI found him hiding out at the shack he was renting near Riverside, California. He was convicted on eight counts of espionage on 28 April 1977, and sentenced by federal district judge Robert Kelleher on 12 September to forty years in prison, initially at Terminal Island, then the Metropolitan Correctional Center in San Diego. On 10 July 1979, he was transferred to the federal penitentiary in Lompoc, California. Escape On 21 January 1980, Boyce escaped from Lompoc. While a fugitive, Boyce carried out 17 bank robberies in Idaho and Washington, hoping to pay for passage to the Soviet Union, and adopted the alias of "Anthony Edward Lester." According to Boyce, he studied aviation, not to flee to the Soviet Union as some suspected, but to rescue Daulton Lee from Lompoc. On 21 August 1981, Boyce was arrested by U.S. Marshals while eating in his car outside "The Pit Stop," a drive-in restaurant in Port Angeles, Washington. Authorities had received a tip about Boyce's whereabouts from his former bank robbery confederates. Return to prison In the spring of 1982, Boyce appeared before Judge Harold Ryan in U.S. District Court in Boise and was sentenced to three years for his escape and 25 years for bank robbery, conspiracy, and breaking federal gun laws. Given an aggregate total sentence of 68 years, he was transferred to United States Penitentiary, Leavenworth. Later that year, Boyce gave a television interview to Ray Martin for Australia's 60 Minutes about the dismissal of Whitlam. After this he was assaulted by fellow inmates, an attack he believed was orchestrated by prison guards. After the attack, he was transferred to USP Marion, where he was held in isolation. In April 1985, Boyce gave testimony on how to prevent insider spy threats to the Senate Permanent Subcommittee on Investigations as part of its Government Personnel Security Program. In 1988, with support from senators, he was transferred, out of solitary confinement, to Minnesota Correctional Facility – Oak Park Heights. He was transferred to ADX Florence in Colorado
