About Earle Cabell
Earle Cabell was an American politician who served as the 48th mayor of Dallas from 1961 to 1964. Cabell was mayor at the time of the assassination of United States President John F. Kennedy and was later a member of the U.S. House of Representatives. He was a conservative Democrat. He and his brothers founded Cabell's Inc., a chain of dairies and convenience stores. Cabell was the youngest of four sons of the then former Dallas Mayor Ben E. Cabell's wife reported that while riding in Kennedy's motorcade through Dealey Plaza, she observed "a rather long looking thing" sticking out of a window of the Texas School Book Depository immediately after the first shot. In 2017, documents declassified under the JFK Records Act revealed that Cabell had been a CIA asset since 1956.
