Another potential riot at the Milwaukee County Jail was quelled by guards in April, Wisconsin Examiner has learned through open records requests. On April 12, correctional officers were notified of a “mass refusal,” with jail residents refusing to enter their cells. One occupant was placed on administrative segregation for attempting to incite a riot, according to emails obtained by Wisconsin Examiner. 

This marks the second known instance this year that unrest has occurred within the jail. Emails sent by Sgt. Tiawana Thompson indicate that at about 12:30 pm on April 12, Officer Brenden Zollicoffer radioed the jail’s master control to report the mass refusal. According to the email exchange, Thompson arrived with Officer Billy Howled and saw that additional Milwaukee County Sheriff Office (MCSO) personnel were already responding to POD 5D, where the refusal was occurring. 

“I noticed occupants either running to their cells, laying down, or standing at their cells,” Thompson wrote in the email, adding that personnel advised that occupant Corey Kirkwood had “incited a riot by closing all cell doors not allowing inmates to get into their cells.” Kirkwood, who was charged in January with sexual assault and trafficking of a minor, was one of several jail residents who appear to have been transferred to other parts of the facility after the April unrest. 

Thompson’s email also reported that “due to this action, occupant Kirkwood will be placed on administrative segregation (Ad-seg), pending discipline as well as being an ongoing investigation.” Another officer was tasked with completing a rules violation report, the email stated.

The Milwaukee sheriff did not respond to questions about the incident and whether Kirkwood remains in administrative segregation, or how he was able to control whether cell doors were open or closed. 

Ten days after the mass refusal, MCSO Correctional Captain Kerry Turner emailed Sgt. Thompson and asked whether paperwork for those moved to administrative segregation had been finished. Turner asked, “Also, have all violations been completed and signed off on by a supervisor? Have the occupants all received a copy of their violation? Please let me know the status of these concerns of mine.” 

It’s unclear what triggered this particular mass refusal incident. Another potential riot was quelled by jail staff in mid-February after one jail occupant, 49-year-old Keenan Brown, allegedly attempted to incite a riot by “shouting to the entire housing unit that the inmates needed to stick up for themselves and that they would not be taken seriously until they started assaulting staff.” Jail staff had learned that Brown used his jail-issued tablet to contact his mother, urging her to reach out to Fox6. When jail staff talked to Brown, he said jail residents weren’t being let out of their cells enough, and that their rights were being violated. At least 20 people were transferred to other parts of the jail after that incident as well. 

During the late summer of 2023, nearly 30 jail residents were charged with disorderly conduct after they barricaded themselves in a library area and refused to return to their cells. The mass action was done to protest “dissatisfaction with their gymnasium time coming to an end and expressing that, generally, they wanted more ‘open’ recreational time,” according to an MCSO press release issued weeks after the unrest occurred. 

The jail has come under increasing scrutiny under multiple sheriffs in recent years. Over a 14-month period from 2022 to 2023, six people died in custody at the jail. In late May, 33-year-old Gabriel Muniz-Jimenez became the second person to die in 2025.  A third party audit detected severe problems with the physical condition of the jail’s booking areas, housing units, use of force policies and practices for monitoring people placed on suicide watch. A recent review by the auditor, the Texas-based company Creative Corrections, found the jail to be in compliance with 71.2% of  proposed corrective actions, with another 28.8% being in partial compliance.

A man who died at the Milwaukee County Jail earlier this week has been identified as Gabriel Muniz-Jimenez, 33. Records from the Milwaukee County Medical Examiner’s Office, obtained by Wisconsin Examiner, show that Muniz-Jimenez was pronounced dead Wednesday at 10:56 p.m. He is the second person to die in the jail so far this year. 

On Thursday, the Milwaukee County Sheriff’s Office (MCSO) reported that an unidentified 33-year-old man had died after his cellmate reported to correctional officers that the man “appeared to be unconscious and in medical distress,” Urban Milwaukee reported.

The sheriff’s office said that the deceased man had been booked into the jail in November on felony methamphetamine possession. Online court records show that Muniz-Jimenez was charged with methamphetamine possession in April 2024 and the court case was filed in July. 

Booking information online shows that Muniz-Jimenez was booked into the jail in late November on methamphetamine charges. Court records showed that Muniz-Jimenez required a Spanish interpreter in court. 

The sheriff’s office announcement this week said officers attempted lifesaving measures including the use of Narcan, which can reverse an opioid overdose. A demographic report from the Medical Examiner’s Office on Muniz-Jimenez labels the cause as undetermined. MCSO has not responded to a request for comment, and the Waukesha County Sheriffs Department, which is investigating the death, declined to identify who died in the jail. The MCSO is a member of the Milwaukee Area Investigative Team (MAIT), which handles officer-involved deaths such as shootings and in-custody deaths. 

The Milwaukee County Jail has garnered controversy for deaths in recent years. The 2022 suicide of 21-year-old Brieon Green was the first of six in a 14-month period, and families of people who died have allied with activists to call attention to the deaths. In March, 48-year-old Joseph Boivin died at Froedtert Hospital after being found by a nurse in the middle of a health emergency at the jail. A jail audit detected numerous issues, including use of force and what the auditors called “dangerous suicide watch practices.”  

A recent review by the Texas-based auditor Creative Corrections found that the jail has come into full compliance with 71.2% of the proposed corrective actions, with another 28.8% being in partial compliance. The jail still needs to fund two new suicide watch cells. Jail officials are renovating housing areas and have said they are updating suicide watch policies.
