In 1965 it was transferred to Immigration and Customs Enforcement which sounds like it was deporting illegals. Finally in 1966 it was taken over by the U.S. Department of Justice so would have been conducting prisoner transfer flights. On 8 August 1967 it was wrecked landing at San Antonio/TX when the gear retracted on roll-out.
