St. Mary's Detention Center Overview

The St. Mary's County Sheriff's Office Corrections Division operates the St. Mary's County Detention and Rehabilitation Center in Leonardtown. The Sheriff's Corrections page describes the operation as a recently expanded and renovated local correctional facility that provides care, custody, control, food, medical and behavioral health care, mental health services, education, rehabilitative programs, offender re-entry support, and medication-assisted treatment. Warden Mary Ann Thompson is listed as Warden, and Captain Michael A. Pilkerton is listed as Assistant Warden.

The detention center is a county jail, not a Maryland DPSCS state prison and not a federal or ICE detention facility. The Sheriff's services page says the facility serves incarcerated individuals awaiting trial, undergoing pre-sentence investigation, sentenced, and people on community supervision. That range is broader than a simple booking lockup, but public lookup still starts with the St. Mary's County jail roster for people physically in local custody.

A historical official budget packet surfaced in research says a 1998 addition raised permanent housing design capacity to 230 beds. Current official rated capacity was not found on the current Sheriff pages reviewed for this build, so current capacity should not be stated as if it were verified.

The official Corrections Division page identifies the detention center, Community Corrections Center, leadership, and division services.

That corrections overview is the core source for treating this facility as the county's primary jail and rehabilitative-services operation.

Address and Phone

The public contact point for the St. Mary's County Detention and Rehabilitation Center is the Sheriff's detention center listing. Research found an extension discrepancy across official or official-looking sources: the Sheriff's contact page lists the detention center at x2200, the app-hosted roster footer lists x72200, and the county directory lists ext. 3200. The safest public citation is the Sheriff's current contact page, with the discrepancy noted when precision matters.

Who Is Held Here

St. Mary's County Detention and Rehabilitation Center holds people in local adult custody. The Sheriff's services page uses the phrase "incarcerated individuals" and states that the facility serves people awaiting trial, people undergoing pre-sentence investigation, sentenced individuals, and people on community supervision. In practice, that means a roster entry may involve a recent arrest, a District Court or Circuit Court case, a local sentence, a violation matter, or a hold connected with another agency.

The jail roster is not the right system after every transfer. A person sentenced to Maryland state prison is searched through the Maryland DPSCS incarcerated individual locator. A federal sentenced person is searched through the BOP inmate locator. Immigration detention is searched through ICE ODLS. St. Mary's County has an ICE Warrant Service Officer memorandum dated March 25, 2025, but that does not make the Leonardtown jail a dedicated ICE detention center.

St. Mary's Facility Lookup

Use the official Detention and Rehabilitation Center Incarcerated Individual Lookup for current local custody. The lookup is free and does not require an account. The public table shows ID, name, age, race, sex, booking date, and links for Charge(s) and Mugshot. It does not publish housing unit, court date, bond, address, medical information, or release date in the inspected public view.

1. Open the official Sheriff's incarcerated individual lookup or the app-hosted lookup.
2. Enter first name, last name, or both. If spelling is uncertain, try last name first.
3. Use View All on the app-hosted interface when starting with a broad search.
4. Review the roster row for ID, name, age, race, sex, booking date, charges, and mugshot access.
5. If no row appears, call the detention center or use the Sheriff's public information process for records not online.

For full custody context, compare the jail roster with Maryland Judiciary Case Search because roster charges can differ from prosecutor-filed court charges. The jail row is a booking record, not proof of guilt and not the final court case record.

Booking and Classification

The Sheriff's public pages do not publish a full booking script, but they do identify the local intake structure. After a St. Mary's County arrest that results in jail custody, the person is taken to the detention center for intake. The jail creates or updates the local custody record, assigns an ID, records the booking date, and publishes certain fields on the public roster when the record is available for public view.

Classification is official and local. The Sheriff's incarcerated-individual services page says all committed incarcerated individuals are classified using an objective system to determine security level and program needs. Classification helps manage the jail population, reduce risk for staff and incarcerated individuals, and route people toward reentry, medical, mental health, substance-use, or program supports when appropriate.

Visitation and ICSolutions

Visitation for St. Mary's County Detention and Rehabilitation Center is video based through ICSolutions. The Sheriff's contact page and visitor guide say family and friends must create an ICSolutions account and schedule the visit. Visits must be scheduled at least 24 hours in advance and up to one week ahead. The visitor guide says each visit lasts 25 minutes, offsite visits are unlimited per week, and all visits are recorded and monitored.

Visitors need a valid email address because cancellation notices are sent by email. The visitor guide also says the detention center should not be called for scheduling or registration problems; ICSolutions video support is the support channel. Taking or posting photos or video of incarcerated individuals is forbidden and can lead to suspended privileges.

The official incarcerated individual contact page gives the county's phone, mail, video visit, and vendor details.

That source is the best starting point before scheduling a visit or setting up phone and video services.

MailGuard, Phone, and Money

Regular mail for incarcerated individuals is handled through Smart Communications MailGuard. Mail is scanned and made available through tablets. The mail address is not the Leonardtown jail address for regular letters. It uses the MailGuard address in Pinellas Park, Florida, with the incarcerated individual's name and booking or ID number clearly printed. Books, periodicals, packages, and money orders follow different rules.

Incoming phone calls to incarcerated individuals are not permitted. Phone service is contracted through ICSolutions Advanced Technology. Money deposits changed under the January 14, 2025 visitor guide: cash is not accepted at the detention center, online deposits go through Access Corrections, and mailed money orders are held for 10 days from date of deposit.

Medical, Mental Health, and MOUD

The Sheriff's services page gives unusually detailed information about health and reentry at the St. Mary's County Detention and Rehabilitation Center. PrimeCare Medical provides clinical and emergency medical services under contract. The page says basic clinical and emergency care is available 24 hours a day, and references Maryland correctional standards under COMAR Title 12, Subtitle 14.

Mental health services use evidence-based screening and assessment tools. Reentry planning involves case managers, a licensed social worker, and peer recovery specialists who work on individualized plans and aftercare. The local MOUD program is a major St. Mary's County detail. The Sheriff's page says the facility volunteered as one of four Maryland pilot local detention centers and began its Medication for Opioid Use Disorder program in September 2020 during the pandemic and expansion work.

Maryland Correctional Services Section 9-603 requires state and local correctional opioid-use-disorder screening, evaluation, medication access, counseling, peer recovery, reentry planning, and reporting. Medication options named by the Sheriff's services page include methadone, buprenorphine, and Vivitrol when clinically appropriate.

The official incarcerated individual services page documents classification, reentry, medical care, mental health care, and MOUD.

That source supports the facility's rehabilitative and health-care description without overstating details that are not published.

Directions, Parking, and Transit

The detention center is on Baldridge Street in Leonardtown near the county government center, District Court, Carter State Office Building corridor, and other local public offices. Official District Court directions nearby say drivers from Route 5 south turn left onto Route 245, drivers from Route 5 north turn right onto Route 245, and then turn right onto Baldridge Street after about half a mile. Visitors from Lexington Park, California, Charlotte Hall, or Mechanicsville generally approach Leonardtown through MD-5 or local connector roads.

Detention-specific parking rates were not published in the located official pages. The nearby District Court page says parking is adjacent to the Carter Building, but visitors should confirm jail visitor parking before travel. St. Mary's Transit System routes serving Leonardtown include Lexington Park to Leonardtown, Leonardtown to Lexington Park, Leonardtown Loop, and Route 5 Express. The visitor guide says lobby doors are secured and visitors must pick up the black phone to contact Main Control.

Public Records and Facility Contacts

Records connected to St. Mary's County Detention and Rehabilitation Center can come from several offices. Current custody and mugshot links start with the jail roster. Broader booking records, videos, radio transmissions, and public information requests go through the Sheriff's records process and NextRequest portal. Court charges, case status, hearings, and dispositions are searched through Maryland Judiciary Case Search and court clerk channels.

The Sheriff's records page says victims of criminal investigations and drivers in motor vehicle accidents may obtain report copies. It lists records contacts for offense reports, accident reports, civil process, warrants, child support, and records supervision. It also says accident reports for involved individuals cost $5.00, while criminal investigation victims are not charged. Reports are usually mailed when available within ten working days, and the public information form includes MPIA timing language for longer production.
