Arizona lawmakers probe prison classification, staffing and MAT after Cimarron unit murders

A legislative ad hoc committee convened July 22, 2025, to examine safety failures inside Arizona prisons after the April 4 killing of three inmates at the Cimarron unit and a broader rise in inmate and staff assaults.

The hearing — led by committee co-chairs including Senator Payne — focused on whether rapid reclassification of inmates out of maximum custody, chronic staff vacancies, contraband and the state’s Medication-Assisted Treatment program contributed to the deaths and deteriorating security. “This hearing is not just about what happened on April 4. It’s about the system that has reached a breaking point,” Senator Payne told the panel.

Why it matters: Committee members and witnesses said multiple failures combined to raise the risk to staff and incarcerated people. Witnesses called for better records access, clearer classification safeguards and additional transparency about the department’s rollout of MAT and other major operational changes.

Key findings and testimony

- The April 4 homicides: Multiple public witnesses and committee members discussed the April 4, 2025, killings at the Cimarron unit, which involved inmate Ricky Wassenaar. Public advocate Donna Hamm told the committee she had earlier warned the department that Wassenaar posed a risk; she also cited media reporting that Wassenaar had previously described possessing a rock and a knife prior to the April attacks. The county medical examiner’s autopsy for a November 2024 death involving Wassenaar was listed as “undetermined,” and county prosecutors later declined criminal charges in that earlier case, the director said.

- Classification and overrides: Witnesses said the department has moved large numbers of inmates out of maximum or restrictive housing into lower custody settings since early 2023. Former and current staff told the committee rapid “overrides” of classification scores and a policy shift away from long-term restrictive housing reduced available maximum beds and placed some high-risk inmates in yards where they had more access to others. Retired warden Stacy Abar testified that “over 1,300 maximum custody inmates” were removed to lower custody, destabilizing populations and contributing to violence.

- Staffing shortages and turnover: Multiple witnesses said staff vacancies have weakened supervision. Advocates and former correctional officers cited a published figure the department reported of roughly 963 vacancies as of July 2025 and described difficulty recruiting and retaining experienced staff. The agency’s director, Ryan Thornell, told the committee vacancies had improved from earlier highs and that some complexes (for example, Lewis Prison Complex) saw vacancy rates fall substantially since 2023, but that other units such as Tucson and Iman remained under strain.

- Medication-Assisted Treatment (MAT): Former staff and advocates criticized how MAT (Suboxone) was implemented. Retired corrections official Travis Scott said the program was embedded in a federal injunction and rolled out without sufficient systems or staffing to ensure supervised dosing, increasing opportunities for diversion and misuse. Director Thornell said the department established a multi-stakeholder steering committee, clinical oversight and additional training during the MAT rollout and that clinicians make individualized treatment decisions.

- Contraband and intelligence gaps: Witnesses — including a former corrections investigator and advocacy groups — described illicit phones, drugs and makeshift weapons in units. The director noted the department formed a contraband interdiction task force, implemented technology such as RFID logging in high-custody areas, and planned additional measures including digital mail scanning.

- Leadership, culture and transparency concerns: Several former wardens and long-tenured corrections staff criticized senior-level turnover and some appointments of leaders with limited in‑facility experience. They also told the committee that operational decisions felt rushed, and that staff morale and trust in leadership had declined. Director Thornell defended many leadership changes as based on organizational needs beyond simply having prior yard experience and urged legislators to tour facilities and review written reports.

Committee direction and evidence requests

The committee pressed ADCRR for documents it had requested in June 2025, including mortality and investigatory materials. Director Thornell said some materials had been routed through the agency’s public records office and that some investigative evidence remains with county prosecutors. He acknowledged delays and apologized that the committee had not yet received all requested materials and agreed to follow up.

Ending

Committee members and witnesses said they intend a deeper, document‑driven review to determine whether policy or statutory changes are needed. Director Thornell agreed to provide additional information and to meet with committee leaders to review homicide case files, classification records and staffing metrics. The committee did not vote on formal measures during the hearing; members said they expect follow-up meetings and may use legislative tools to require further transparency or statutory change.

Discussion vs. decisions

- Discussion points: causes of the Cimarron murders; role of classification overrides; staffing shortages; MAT design and diversion; contraband networks; leadership turnover and culture. - Directions requested: the director agreed to provide requested documents, meet with committee chairs for a data review, and to supply additional reports and clarifications on classification decisions and homicide investigations. - Formal decisions: none recorded at the hearing; the committee signaled intent to continue oversight and to consider policy or statutory follow-up.

Clarifying details extracted from testimony

- Staffing: the department reported about 963 vacancies as of July 2025 (witnesses cited the July figure); this was described as a major operational constraint. - Homicides: committee was told nine homicides in the ADCRR system occurred in the 12‑month span referenced at the hearing; three of those were the April 4 Cimarron deaths. - Custody counts: witnesses and department figures discussed a reduction from roughly 1,300+ maximum/restrictive-housing beds in January 2023 to fewer than 300 by late 2023 (figures were presented during the hearing and discussed as part of the classification review). - MAT enrollment: the department reported rolling MAT up to roughly several thousand people statewide (witnesses said the program rose from several hundred to several thousand during 2023–2024 as it was implemented under court requirements).
