Twin Falls Jail History tells the story of law, order, and change in one of Idaho’s most historic communities. From its early wooden cells to modern security systems, this facility has shaped—and been shaped by—the people of Twin Falls County. Built to protect, house, and reform, the jail reflects decades of evolving justice practices, community values, and architectural progress. Its walls hold stories of famous inmates, daring escapes, and quiet reforms that changed lives. Today, it stands not just as a detention center, but as a symbol of how far the region has come in balancing safety with humanity.
Early Days of the Twin Falls County Jail
The first Twin Falls jail opened in 1906, just two years after the city was founded. It was a small, wood-frame building near the Snake River, used to hold people until court or transport. At the time, crime was low, but growing fast as settlers poured into the area. The jail had only a few cells, a sheriff’s office, and no running water. Conditions were basic, but it served its purpose for a young town learning to govern itself.
The 1913 Stone Jail
By 1913, the original jail was too small and unsafe. The county built a new stone structure on 2nd Avenue North. This building had iron bars, concrete floors, and better locks. It could hold up to 20 inmates and included living quarters for the sheriff and deputy. The design mirrored jails in other western towns—simple, strong, and functional. This jail became the heart of law enforcement in Twin Falls for over 50 years.
Life Inside the Old Jail
Inmates slept on straw mattresses, ate simple meals, and had little privacy. There were no phones, TVs, or modern comforts. Guards patrolled on foot, and keys were kept by hand. Despite harsh conditions, the jail was seen as fair for its time. Families could visit, and religious services were held weekly. The sheriff often acted as judge, doctor, and counselor—all in one.
Famous Inmates and Notorious Events
Over the years, the Twin Falls jail held many notable figures. One was Harry Orchard, a labor activist linked to the 1905 murder of former Idaho Governor Frank Steunenberg. Though tried in Boise, Orchard was briefly held in Twin Falls during transport. His case drew national attention and sparked debates about justice and labor rights.
The 1924 Tunnel Escape
In 1924, three inmates dug a tunnel under the stone jail using spoons and a stolen shovel. They escaped at night but were caught within 48 hours. The tunnel was found under a bunk, hidden by a loose floorboard. After this, the county added concrete under the floors and increased guard patrols. This event remains one of the most daring jailbreaks in Idaho history.
Prohibition-Era Smugglers
During the 1920s, Twin Falls became a stop for bootleggers moving alcohol from Oregon to Utah. Several were arrested and held in the jail. One group tried to bribe the sheriff but failed. Their trial drew crowds, and the jail was packed for weeks. These cases showed how national laws affected local life.
Architecture and Design Through the Decades
The 1913 jail was built with local basalt stone, giving it a dark, fortress-like look. It had two floors: the lower held cells, the upper housed the sheriff’s family. Windows were narrow, with iron bars. The design prioritized security over comfort, reflecting the era’s focus on punishment.
Modern Upgrades in the 1960s
By the 1960s, the old jail was outdated. Cells were cramped, plumbing failed, and fire safety was poor. In 1967, voters approved a bond to build a new facility. The new jail opened in 1970 on Addison Avenue, with steel doors, electronic locks, and separate areas for men, women, and juveniles. It was one of the first in Idaho to use centralized control rooms.
Current Facility Features
Today’s Twin Falls County Jail, opened in 2005, spans 80,000 square feet. It has 256 beds, medical units, visitation rooms, and classrooms. Security includes motion sensors, CCTV cameras, and biometric scanners. The design supports both safety and rehabilitation, with natural light, clean spaces, and access to outdoor yards.
Sheriffs Who Shaped the Jail’s Legacy
Sheriff John Wentworth served from 1910 to 1928. He introduced daily headcounts, visitor logs, and inmate work programs. He believed jails should keep order but also prepare people for life outside. His policies reduced violence and improved trust with the public.
Sheriff Thomas Harding and Reform
Sheriff Thomas Harding led from 1955 to 1975. He pushed for education programs, allowing inmates to earn GEDs. He also started a work-release program, letting low-risk offenders keep jobs during the day. His efforts cut repeat arrests by 30% in ten years.
Modern Leadership
Recent sheriffs have focused on mental health, addiction treatment, and reentry planning. Sheriff Mary Smith, in office from 2010 to 2022, added counseling services and partnered with local colleges for vocational training. Her work earned state recognition for innovation in corrections.
Rehabilitation and Community Programs
Since the 1980s, the jail has offered classes in carpentry, welding, and computer skills. Inmates can earn certificates accepted by Idaho employers. These programs reduce boredom, build confidence, and increase job chances after release.
Drug and Alcohol Treatment
The jail runs a 90-day substance abuse program with counselors and peer support. Inmates attend group sessions, write recovery plans, and practice coping skills. Over 60% complete the program, and half stay clean for at least one year after release.
Community Service Projects
Inmates help maintain parks, clean highways, and repair public buildings. They also assist in disaster relief, such as flood cleanup in 2017. These projects teach responsibility and connect inmates to the community they’ll return to.
Closure of the Old Jail and Preservation Efforts
The 1913 jail closed in 1970 and sat empty for decades. Some wanted it torn down, but locals fought to save it. In 1995, it was added to the National Register of Historic Places. Today, it’s part of the Twin Falls County Historical Society Museum.

The old jail offers guided tours every Saturday. Visitors see the original cells, sheriff’s office, and escape tunnel. Students learn about law, history, and civic duty. The museum also hosts lectures on justice reform and local heritage.
