Natrona County Jail Roster — is a public tool that allows anyone to check who is currently in custody at the Natrona County Detention Center in Casper, Wyoming. The website NatronaCourt.us collects publicly available information about current and recent inmates of the county. Additionally, data can be obtained through the official sheriff's website, by calling the detention center, or by visiting in person. The roster is maintained by the Natrona County Sheriff's Office — one of the largest law enforcement agencies in the state of Wyoming, serving approximately 80,000 residents. The list is regularly updated and reflects individuals who are actually held in the facility at the time of viewing.
Search Current Inmates in Natrona Jail
There are several ways to find out if a specific person is in custody at the Natrona County detention center.
Online Search
- Visit NatronaCourt.us to find publicly available information about inmates.
- Go to the Detention Center page on the official county website — there you will find links to the roster and related resources.
- To search, enter the full legal name (last name and first name) or booking number, if known.
- If the system only supports list viewing, use the browser's search function (Ctrl+F or Cmd+F) to quickly find a last name.
Juvenile offenders are not displayed in the public roster — this information is confidential according to Wyoming law.
Phone Inquiry
Call the detention center directly. The operator can confirm if a specific person is held if you provide the full name.
Personal Visit
You can visit the lobby of the Detention Center. Note: the detention center is a 24-hour facility, but there are periods of administrative lockdown during which public activities are suspended. Check the current reception schedule before visiting.

Additionally, you can check for active warrants on the Natrona County warrant search page, which is updated every business day and covers warrants from the 7th Judicial District Court and the 7th Judicial Circuit Court.
Find Natrona Jail Booking Records Online
A booking record is created every time a person is officially admitted to the detention center. It is the first document that records the fact of being held in custody.
During the booking process, the following data is generated:
- Unique booking number
- Date and time of admission
- Charges presented
- Name of the arresting agency
- Identification details of the person — name, date of birth, physical characteristics
Part of this information automatically enters the public inmate roster. To obtain a full record, which may contain additional details, there are two ways.
First, submit an official public records request. Wyoming law (Public Records Act, Wyo. Stat. § 16-4-201 et seq.) defines which documents are public. The request form for the Sheriff's Office can be filled out on the Records Request page. Not all records qualify as public — some may be restricted.
Second, for court materials related to criminal cases, use the county court case search, which covers civil, criminal, family, and probate cases. Juvenile and adoption cases are confidential.
If the person has already been transferred to a state-level facility, use the Wyoming Offender Locator of the Wyoming Department of Corrections.
Search the Natrona Jail Roster by Last Name or Booking Number
The roster supports two main search methods.
Search by Last Name
Enter the person's last name in the appropriate field. If the system allows, add the first name to narrow the results. Some practical tips:
- Use the exact spelling of the legal name — hyphenated or apostrophized last names may be processed differently.
- Try just the last name if the full name yields no results: the name might be recorded differently than you expect.
- Special characters are generally not allowed in the search field.
Search by Booking Number
This method is the most accurate. The booking number is a unique identifier assigned during booking. It may be provided to relatives during the first call from the detention center or when contacting the facility.
If the Search Yields No Results
- Check the spelling — even one extra letter can interfere.
- The person may have just been delivered, and the record has not yet appeared in the system.
- The person may have already been released or transferred to another facility.
- Call the detention center directly — staff can confirm custody status verbally.
- Check the warrant list — a warrant may have been issued, but the arrest has not yet occurred.
Jail Roster Updates and Search Limitations in Natrona
The Detention Center inmate roster is not an archive of all past arrests. It only reflects those individuals who are in custody at the time of the last update.
Update Frequency
Data is updated regularly throughout the business day. However, it may take from a few minutes to several hours between the actual booking of a person and the appearance of the record in the online roster — this depends on the facility's workload and the time of day.
Known Limitations
| Limitation | Explanation |
|---|---|
| Delay after Booking | A recently delivered person may not appear immediately — the booking process takes time. |
| Disappearance after Release | Once a person is released or transferred, the record disappears from the current roster. |
| Confidential Records | Juveniles and certain categories of detainees are not displayed in the public list. |
| Technical Failures | Periodic server maintenance or data entry errors may temporarily affect accuracy. |
For state-level historical criminal records, contact the Criminal Records Unit at the Wyoming Division of Criminal Investigation. According to Wyo. Stat. § 7-19-107(c), all felonies and serious offenses are recorded through the submission of fingerprint cards.
