The man wanted for one of the biggest bank robberies in Cleveland history lived "an unassuming life" in a Massachusetts suburb for more than 50 years before his death earlier this year. Theodore "Ted" Conrad allegedly stole $215,000 from the Society National Bank in Cleveland where he worked as a teller on July 11, 1969. Conrad, who was 20 at the time of the alleged crime, vanished and left investigators "perplexed" for years. Five decades later, US Marshals believe they have finally identified the man responsible for the crime. Conrad, who assumed the alias Thomas Randele after the heist, moved to Lynnfield, Massachusetts, in 1970. Conrad died of lung cancer in May at age 71. Lynnfield, a suburb located north of Boston, is the setting of the 1968 Steve McQueen film The Thomas Crown Affair, in which a millionaire businessman commits a robbery for sport. US Marshals say Conrad was "obsessed" with the film and allegedly "bragged to his friends about how easy it would be to take money from the bank" if he tried. Authorities claim he even told his inner circle that "he planned to do so." An obituary for Conrad said that while living in the Bay State, he worked his way up the management ladder at a country club in Pembroke, before moving on to sell luxury cars at Woburn Foreign Motors, Range Rover, and Volvo for nearly 40 years. Conrad was married to Kathy (Mahan) Randele and had one daughter, Ashley Randele.
