The man was William Zinselmeier, who died in early January 2023 inside the Jefferson County Jail in Missouri. His family has now filed a wrongful death and civil rights lawsuit that accuses jail officers and contracted medical staff of ignoring repeated pleas for help as his diabetes and other health problems spiraled in the days before he died.
The Allegations At The Center Of The Case
The complaint, filed in federal court in Missouri and posted by DocumentCloud, names Jefferson County, Sheriff Dave Marshak, several corrections officers and VitalCore Health Strategies, the private company that provides medical care inside the jail, as defendants. The suit was first reported by Law&Crime.
According to the lawsuit, Zinselmeier entered the Jefferson County Jail in March 2022. At intake, he reported that he lived with diabetes and hypertension and needed prescription medication to manage both conditions. The complaint states that jail and medical staff documented his conditions but later failed to provide consistent care.
By the start of January 2023, the lawsuit says, his health had sharply declined. He allegedly became, in the complaint’s words, “too sick” to get out of bed or eat. Other people detained in the same housing unit began to worry he might not survive.
‘I Feel Like I’m Gonna Die’
The most detailed allegations in the complaint focus on the final week of Zinselmeier’s life. The filing describes a man who could not keep down food or water and who relied on others in the unit to push the emergency call button and summon assistance.
In a passage quoted by Law&Crime, the complaint alleges:
“As the days passed, Mr. Zinselmeier’s condition worsened and fellow detainees became increasingly concerned about Zinselmeier, as he was unable to drink water or eat food without immediately vomiting. Both Mr. Zinselmeier and other inmates requested medical help, medication, and voiced their concerns for Mr. Zinselmeier’s serious medical needs, including warning guards and nurses, and repeatedly pressing the emergency call button. Zinselmeier said several times ‘I feel like I’m gonna die.’ His roommate told guards he was ‘dying.’ Despite these serious complaints, and requests for his prescription medication and treatment, Jefferson County Jail correctional officers and VitalCore medical staff ignored the pleas.”
One fellow detainee asked a guard to bring Zinselmeier his medication, according to the suit. The officer allegedly replied that “if he wants his medicine he can get up and come get his medicine.”
At that point, the complaint argues, staff knew that a detainee with serious, documented medical needs reported feeling near death, yet responded with “deliberate indifference.” The defendants have not publicly answered the detailed allegations in the complaint. None of the claims has been tested in court.
Ten Hours On The Floor
The lawsuit says that roughly ten hours before his death, Zinselmeier fell out of his jail bunk and became unresponsive. Instead of calling 911 or starting medical treatment, the complaint alleges, corrections staff “milled in and out” of the cell while he remained on the floor.
According to the filing and the account reported by Law&Crime, it was his cellmate who finally realized that something was critically wrong. Around 3:40 a.m. on a January morning, the cellmate noticed that Zinselmeier was not breathing and pushed the emergency button.
Medical staff arrived within minutes, the lawsuit says, but they pronounced him dead shortly after 4 a.m. An autopsy listed his cause of death as “hypertensive cardiovascular disease” with diabetes as a significant contributing factor, according to the Law&Crime report, citing the family and the complaint.
Attorney Marj J. Pedroli, who represents the family, argues in the filing that his death was both “foreseeable” and “preventable.” The core claim is that repeated verbal warnings from Zinselmeier and other detainees, combined with his known medical conditions, should have triggered urgent evaluation and treatment.
What The Lawsuit Claims About Rights Violations
The complaint seeks damages on two main theories. First, it alleges wrongful death under Missouri law. Second, it asserts that the jail, sheriff’s office and medical contractor violated Zinselmeier’s rights under the Eighth and Fourteenth Amendments to the U.S. Constitution.
In the prison and jail context, the Eighth Amendment prohibits “cruel and unusual punishments.” For people who have been convicted, the Supreme Court has held that this includes a right to basic medical care. In the 1976 case Estelle v. Gamble, the Court ruled that “deliberate indifference to serious medical needs” of incarcerated people violates the Constitution.
Later decisions extended similar protections to pretrial detainees, who are held under the Fourteenth Amendment’s Due Process Clause rather than the Eighth Amendment. To win on that kind of claim, plaintiffs typically must show that officials knew of a serious medical risk and disregarded it.
Pedroli’s lawsuit argues that standard was met in Zinselmeier’s case. The filing points to his documented diagnoses, alleged repeated vomiting, the warnings from his cellmate, his own reported statement that “I feel like I’m gonna die,” and the claim that he lay unresponsive on the floor for hours without a 911 call.
The defendants have not yet presented their version of events in the court docket. It remains to be seen whether they will dispute the timeline, the level of knowledge staff had, or the medical conclusions drawn by the family’s experts.
Jail Deaths And Medical Care In Context
While the details in this case are specific to Jefferson County, the broad concerns it raises about medical care behind bars are not unique. Federal data show that illness has been the leading cause of death in local jails for years.
According to the U.S. Bureau of Justice Statistics, illness-related causes accounted for the largest share of jail deaths between 2000 and 2019, both in absolute numbers and as a percentage of all fatalities in custody (BJS mortality tables). Many facilities, particularly in smaller counties, contract with private providers like VitalCore to manage that medical risk.
Civil rights attorneys and advocates have long argued that these arrangements can create incentives to limit care, especially for chronic conditions like diabetes that require consistent monitoring and medication. VitalCore is one of several companies that operate in that space. In this case, the lawsuit contends that both the company and county officials failed to put adequate policies and training in place to protect people with serious medical needs.
Those institutional claims will likely become central as the case moves forward. Courts often look not only at what individual officers did, but also at whether the system around them made lapses more likely, for example through understaffing, poor recordkeeping or weak medical protocols.
What Officials And The Family Have Said
Jefferson County officials have not yet given a detailed public account of what happened in the hours before Zinselmeier died. Law&Crime reported that the Jefferson County Sheriff’s Office did not immediately respond to its request for comment, and that VitalCore declined to comment to local station KTVI.
Zinselmeier’s daughter, Kristen, told KTVI that she sees the lawsuit as a way to honor a request her father made from inside the jail.
“My dad told me, ‘If I pass away in here, just make sure that it doesn’t happen to nobody else,'” she said. “That’s what I’m doing.”
The complaint does not specify an exact dollar amount of damages. It asks the court to award compensation and to order changes in policies and training at the jail and at VitalCore so that people with serious chronic illnesses receive timely care.
As of now, much about Zinselmeier’s final days is known only through the lawsuit and the accounts of other detainees. Future court filings could bring medical records, surveillance footage and staff testimony into the public record, which may confirm or contradict the family’s narrative.
For the moment, the court file contains one central factual dispute that remains unresolved: whether a man who said, “I feel like I’m gonna die” was met with the level of care the Constitution requires, or with the indifference his family now alleges.
