The Southwest Idaho Juvenile Detention Center (SWIJDC) is a medium to low-security detention center located at 222 N 12th Ave Caldwell, ID that is operated locally by the Juvenile Justice Department and holds youths awaiting the determination of punishment for the crimes of which they are accused. Most of the adolescents are here for less than two years.

The juvenile justice system differs from the adult system, focusing on rehabilitation and recognizing the developmental differences in juveniles. It aims to protect both the child and the public and helps juveniles become productive adults.

Juveniles are detained if they pose a threat, may miss court, or violate court orders. Parental involvement is crucial for effective supervision and rehabilitation.

Key differences in terminology include "taken into custody" instead of "arrest" and "supervision" instead of "probation." Referrals usually come from law enforcement, and an intake social worker decides the juvenile's placement. An inquiry can lead to dismissal, corrective action, or court involvement.

The process includes a plea hearing, possible evaluations, a pre-trial conference, a fact-finding hearing, and a dispositional hearing to determine the case's outcome. Parents may need to cover associated costs.

Juvenile detention, as part of the juvenile justice continuum, is a process that includes the temporary and safe custody of juveniles whose alleged conduct is subject to court jurisdiction who require a restricted environment for their own and the community’s protection while pending legal action*. Juvenile detention may range from the least restrictive community based supervision to the most restrictive form of secure care.

Out of a twenty-four hour day you go to school for five hours. After school you will get an hour of gym, then later on in the day you get an hour of leisure time. In the old facilities, the cells are 8 feet by 10 feet and there are 18 of these cells with 2 holding cells. In the new facilities, the rooms are 8 feet by 5 feet, there are 60 of these new cells so there’s always room. There’s one window in your room you are forbidden to look out of it unless told to. You can never trust the food because it’s made at the Canyon County Jail and you never know what those inmates might put in it or do to it. These are some descriptions of the beautiful clothes that you get to wear; the pants are green and white striped, orange, and blue, the shirts are dark green, white, light green, and orange. The only items that you are allowed in your cell is; one book, one bible, one deck of cards, and any of your mail. Your parents and grandparents can visit you on Wednesday and Sunday for one hour. You get your blankets at 7:00 p.m. and have to fold them and put them outside your cell at 5:30 a.m. You love your blankets because it gets pretty cold in here. It’s a constant 68 degrees Fahrenheit and even colder after you get out of the shower. You must obey all rules and the staff and respect them and the other juveniles if not you will be put in lock down.

The critical components of juvenile detention include:

  • Screening to ensure the appropriate use of detention,
  • Assessment to determine the proper level of custody, supervision and placement,
  • Policies that promote the safety, security and well being of juveniles and staff,
  • Services that address the immediate and/or acute needs in the educational, mental, physical, emotional and social development of juveniles.

The mission of the Southwest Idaho Juvenile Detention Center is to furnish architecturally secure detention for those youths within Idaho’s Third Judicial District who have violated the law and present a threat to the community, subject to the determination of the courts. Further, the Center shall be an integral part of the Juvenile Justice system as it exists in Canyon County and all participating counties.

SWIJDC is committed to uphold and follow the guidelines of the Juvenile Justice and Delinquency Prevention Act which are contained in the four core requirements, which are:

  • Deinstitutionalization of Status Offenders
  • Jail Removal
  • Sight and Sound Separation of Juvenile from Adult Offenders
  • Disproportionate Minority Contact

SWIJDC is also committed to support the tenets of the “Balanced Approach,” upon which the Idaho Juvenile Corrections Act is based. Those are:

  • Community Protection,
  • Accountability, and
  • Competency Development.
Programs

ARISE Program

in approximately 2013, Officer Muntaga Bah found information about the ARISE program, and became a faciltator. The Arise program is used to teach the residents topics including, but certainly not limited to fatherhood, gang resistance, anger management, healthy lifestyles, self esteem, nutrition, hygiene, finances, etc.

Horses!

Several times per year, Officer Candy Martilla teaches the residents about horses in the classroom, and then actually brings three of hers in for the kids to groom and ride. At the end of “Horse Week,” parents can come in and watch their son or daughter ride.

Bikes!

The Juvenile Probation Community Service Coordinator, Ross Garven, brought a load of bikes in for our residents to triage, fix, salvage or do whatever we could with them. Officer Nathaniel Ashby has been our resident expert in this program. The bikes are then donated to needy families.

Small Engines

Deputy Director Sean Brown spearheaded a small engine “repair” group. We have had several donations, and the kids dig into the engines to see what makes them work. Some things actually do get repaired, but there are no promises! Staff have used some of their own equipment as guinea pigs, with surprisingly good results.

Pat Andersen School Garden

In Spring 2011, the SWIJDC began the Pat Andersen School Garden with a grant from the Idaho State Department of Education and through the help of more than a dozen local sponsors who donated seeds, soil, mulch, plants, fertilizer, irrigation supplies, lumber and other items.

The garden acts as an outdoor classroom for the juvenile detainees and gives them a hands-on experience as they work towards the common goal of creating a thriving vegetable garden.

Under the direction of Garden Coordinator Craig Olsen, the Pat Andersen School Garden has harvested over 6,000 pounds of produce that has been donated to charities across Canyon County.

Inmate Locator

Juvenile facilities overseen by Canyon County do not publish the names of the offenders housed in their facility. As such, there is no public forum for this information.

Frequently Asked Questions

Southwest Idaho Juvenile Detention Center (SWIJDC) - FAQs about Juvenile Detention Centers

  1. What is a juvenile detention center?
    A juvenile detention center is a secure facility designed to house minors who have been arrested, charged, or convicted of a crime. Unlike adult jails, these centers focus on rehabilitation, education, and structured supervision. Youth housed in these facilities may be awaiting trial, serving short-term sentences, or completing mandated treatment programs aimed at reducing delinquent behavior.

  2. How does a juvenile detention center differ from an adult jail?
    Juvenile detention centers differ from adult jails in their approach to discipline, rehabilitation, and environment. They prioritize counseling, education, and structured activities over punitive measures. While adult jails emphasize punishment and security, juvenile facilities are designed to address the root causes of delinquent behavior, such as trauma, lack of parental guidance, or substance abuse issues.

  3. Who can be sent to a juvenile detention center?
    Juvenile detention centers house minors under 18 who have been arrested for criminal activity, ranging from status offenses (such as truancy or curfew violations) to serious felonies like robbery or assault. Some youth may also be placed in detention for violating probation, running away from court-mandated programs, or awaiting transfer to another facility.

  4. What types of offenses lead to juvenile detention?
    Youth may be detained for a variety of offenses, including property crimes (theft, vandalism), drug-related offenses, assault, gang activity, or firearm possession. In some cases, juveniles are detained for non-criminal behavior, such as repeatedly skipping school or running away from home. The severity of the offense, prior record, and risk level typically determine whether a juvenile is detained or placed in an alternative program.

  5. How long do juveniles stay in detention centers?
    The length of stay depends on the case. Some juveniles are held for a few days or weeks while awaiting trial, while others may serve months or years depending on their sentence. Youth placed in long-term detention typically participate in rehabilitation programs, educational courses, and mental health counseling. Courts may also mandate step-down programs, where youth transition into community-based supervision before full release.

  6. Are juvenile records sealed after release?
    In many states, juvenile records are sealed or expunged once the individual reaches adulthood, provided they meet certain conditions. However, serious offenses such as violent felonies or sex crimes may remain on record, potentially affecting future employment, housing, and educational opportunities. In some cases, a juvenile may petition the court to have their record expunged after demonstrating rehabilitation.

  7. Do juveniles in detention attend school?
    Yes, most juvenile detention centers provide on-site educational programs that allow youth to continue their schooling while in custody. These programs may include core academic subjects, GED preparation, and vocational training. Some facilities work with local school districts to ensure that credits earned in detention transfer back to public schools upon release.

  8. Can family members visit juveniles in detention?
    Yes, but visitation policies vary by facility. Families typically need to schedule visits in advance, follow strict security protocols, and comply with dress code regulations. Some detention centers offer video visitation or family counseling sessions to strengthen relationships before the juvenile is released. Regular contact with family members can significantly reduce recidivism and improve rehabilitation outcomes.

  9. Are juveniles allowed to make phone calls?
    Most juvenile detention centers allow monitored phone calls, though the frequency and duration depend on facility rules, the youth’s behavior, and their case status. In some cases, juveniles may call only pre-approved family members or legal representatives. Facilities may also restrict calls if an inmate violates behavioral rules.

  10. What rehabilitation programs are available?
    Programs often include substance abuse counseling, anger management, cognitive-behavioral therapy, vocational training, and life skills workshops. These services are intended to help juveniles develop positive coping mechanisms, make better decisions, and reintegrate into their communities upon release. Some centers also offer mentorship programs where at-risk youth receive guidance from former inmates or community leaders.

  11. Are juveniles placed in solitary confinement?
    While some facilities still use room confinement or restricted housing as disciplinary measures, prolonged solitary confinement for juveniles is widely discouraged due to its negative psychological effects. Many states have passed laws limiting or banning solitary confinement for minors, encouraging the use of alternative discipline methods such as behavioral interventions and conflict resolution programs.

  12. Can juveniles be transferred to adult prison?
    In some cases, juveniles may be tried as adults for severe offenses, such as murder, armed robbery, or sexual assault. If convicted, they can be transferred to adult prison upon turning 18. Some states allow judges to reconsider these transfers based on the juvenile’s rehabilitation progress, age, and psychological evaluations.

  13. What rights do juveniles have in detention?
    Juveniles have the right to education, medical care, legal representation, and protection from abuse. They are also entitled to due process, meaning they cannot be detained indefinitely without a hearing. Inmates must be provided with access to rehabilitative services and fair treatment under the law. Any allegations of abuse or mistreatment must be investigated by oversight agencies.

  14. How do juveniles reintegrate into society after detention?
    Many juvenile detention centers offer reentry programs, including mentorship, transitional housing, probation supervision, and vocational training. Youth are often connected with caseworkers, social services, and education programs to help them successfully reintegrate. Some facilities also arrange family reunification counseling to strengthen support systems at home.

  15. What happens if a juvenile violates probation after release?
    If a juvenile violates probation, consequences can range from increased supervision and mandatory counseling to community service or re-detention. In severe cases, the juvenile may be returned to detention or sent to a more restrictive program. Courts typically evaluate the circumstances of the violation, the individual’s progress, and any external factors before making a decision.
