Leavenworth United States Penitentiary

Opened in 1903, Leavenworth United States Penitentiary is a medium security penitentiary which also has a nearby minimum security prison camp.  USP Leavenworth is located in Leavenworth, Kansas, approximately 25 miles from Kansas City.  Between the penitentiary and satellite camp, the facilities have a total inmate population of 1,845 male prisoners, with 1,397 inmates at the penitentiary and 448 inmates at the camp.  Despite the fact that Leavenworth has an inmate population of 1,845 offenders, the camp was only designed to house 398 offenders while the penitentiary was designed to hold 1,611 offenders.  USP Leavenworth was originally a maximum security prison, being known as the largest maximum security federal prison in the United States.  However, this changed when the penitentiary was downgraded to a medium security prison in 2005.

At USP Leavenworth, all offenders are given the opportunity of self improvement.  Leavenworth encourages inmates to work towards self improvement by providing a variety of programs and services.  All inmates are required to participate in either work or education.  Educational courses include General Education Development, Adult Continuing Education, English as a Second Language, Post-Secondary Education, Vocational Training and Apprenticeships, release preparation, and parenting classes.  Inmates not assigned to education will be assigned to work.  Some common work assignments include cooks, bakers, butchers, plumbers, welders, mechanics, painters, tutors, clerks, and orderlies.  Recreational activities are also available for the benefit of the inmates.  Recreation provides prisoners with leisure time to do activities such as crafts, softball, walking, and music time.  

In 1910, there was an incident where several prisoners escaped.  Inmate Frank Grigware along with 5 other prisoners escaped by crashing through the prison gates with a stolen locomotive.  All the escapees were quickly caught, however Grigware managed to flee to Canada.  Grigware even became the mayor of a Canadian town called Spirit River.  In 1933, Grigware was finally discovered by the Royal Canadian Mounted Police.  The US eventually dropped their extradition request and as a result Grigware never returned back to the United States.  Grigware died in Alberta in 1977.  Another prisoner, Basil Banghart, has escaped Leavenworth on 3 separate occasions.  On September 5th of 1930, Carl Panzram, was hanged at Leavenworth.  Panzram was a serial killer who was given a federal death sentence.  In addition, two other executions have taken place at Leavenworth.  Robert Suhay and Glenn Applegate, both under a death sentence for murder, were hanged at Leavenworth on August 12th, 1938.
