At the plea hearing, Mangum admitted that, on June 20, 2017, he was in the custody of the federal government and imprisoned at the Gerald Hinzman Center in Cedar Rapids, Iowa.  He further admitted that on that day he left the Gerald Hinzman Center to go to work, but did not return to the Center on that day.  Mangum was later arrested by the United States’ Marshal Service on July 12, 2017.       

Mangum was sentenced in Cedar Rapids by United States District Court Judge Linda R. Reade.  Mangumwas sentenced to 18 months’ imprisonment.  A special assessment of $100 was imposed.  He must also serve a 3-year term of supervised release after the prison term.  There is no parole in the federal system.
