One mark per person, by the year they died. Choose the box at the side to see every decade. Coverage is uneven: recent deaths come mostly from local news since 2000, older ones from official lists and historical newspapers, so the shape shows what was recorded as much as how many people died.
The Mississippi Department of Corrections (MDOC) runs the state prisons. It publishes no list or report of the people who die in them. Its annual report, which covers the state fiscal year from July to June, counts deaths only as one "exit type" among people leaving custody, with no names, places or causes.1 Its newsroom puts out a release about a death only now and then. In August 2018 one death was announced on the department's website but never sent to reporters, and Mississippi Today had to file a public records request to get a list of that year's deaths.23
Under state law, the death of anyone confined in a prison, jail or correctional institution is a death "affecting the public interest" that the county medical examiner must investigate. County coroners are elected and work alongside a State Medical Examiner.4 The state crime lab does the autopsies in custody deaths, and in 2018 a backlog there of several years left families waiting for answers.2 Inside the prisons, MDOC's own Corrections Investigation Division investigates deaths, sometimes together with the Mississippi Bureau of Investigation (MBI).5 In 2022 the U.S. Department of Justice found that the division's reports at Parchman mostly just compiled statements and rarely looked into what had happened.6
County sheriffs run Mississippi's jails. No state law requires a jail to track or report deaths, the state does not license or inspect local jails, and the MBI examines only some jail deaths.7 No statewide list of jail deaths is published. The Southern Poverty Law Center had to send public records requests to every sheriff for its 2026 database, and it reported that 28 of the state's 82 counties refused to provide data.8
For the federal Death in Custody Reporting Act, the Division of Public Safety Planning in the Department of Public Safety collects the data. MDOC sends it a spreadsheet of prison deaths every quarter. But the division's own plan says local and county law enforcement agencies are "not actively participating" and that no state law requires them to report.9 In 2023 filings with federal authorities, Mississippi admitted that local jail deaths were largely missing from its reports. Over five years of national records, it was one of four states with locally run jails to report fewer than 10 jail deaths.7
Immigration detention in Mississippi includes the Adams County Correctional Center in Natchez, which CoreCivic runs under contract with U.S. Immigration and Customs Enforcement. ICE announces a death in a news release and later posts a detainee death report. When a man died there in December 2025, the first release spoke only of a medical emergency, and the report two months later said he had tried to hang himself.10 By the Death Penalty Information Center's count, Mississippi has executed at least 25 people since 1976 and at least 351 before then.11
MDOC's only published yearly figure is the number of people whose release from custody was a death. The 2015 annual report has no deaths line at all, because deaths were folded into "other."23 Later reports list 68 deaths for fiscal 2024 and 87 for fiscal 2025, with no names or causes.2425 The death lists MDOC releases on request have also lost detail: the records it gave Mississippi Today in 2018 named no specific causes, although its records for 2012 to 2017 had.3
How a death is classified can also be wrong or slow to change. Reporters found three prison homicides missing from federal and state reports.18 Since 2015, the state medical examiner has ruled another 21 prison deaths "undetermined."19 When Melvin Cancer died at Central Mississippi Correctional Facility in 2025, officials told his family he had a heart attack. In February 2026 reporters learned that he had died of blunt force trauma, and a state report to the Justice Department described an altercation with officers.26
The jail numbers are weaker still. The state has admitted that its federal reports leave out most local jail deaths.7 Its own reporting plan says many agencies call the deaths its staff find through their own research inaccurate and refuse to verify them.9 The Southern Poverty Law Center found county records that left out deaths reported by the news media, the Department of Public Safety or the Justice Department.8 It also found that the Hinds County sheriff's records did not match the state's.22
