Geidel began his sentence at the
Sing Sing prison. His sentence was shortened due to good behavior and he was nearing a possible parole hearing, but doctors then found Geidel to be
legally insane in 1926. He was then moved to the
Dannemora State Hospital for the Criminally Insane, where he was confined until 1972. He was then moved to the
Fishkill Correctional Facility. Here, Geidel lived in a unit designed for elderly inmates that more resembled a dormitory rather than a prison. As Geidel's tenure in prison went by, he developed a rapport with prison officials, who sometimes took him out to a
baseball game, or other outings. Geidel was granted parole in August 1974, but the then-80-year-old inmate did not want to leave. Having lived in prison for 63 years—his entire adult life—and having no family, he believed he would not make it on the outside, having become
institutionalized. He chose to remain in prison for almost six more years. == Release ==
