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.
Delaware has no county or city jails. The Delaware Department of Correction runs the state's four prisons, and it holds people awaiting trial as well as people serving sentences.12 The U.S. Bureau of Justice Statistics counts Delaware's prisons and jails as one integrated system; by its count, at least 287 people died in the department's custody from 2001 through 2019, at least 33 of them by suicide.3 Children are held by the Division of Youth Rehabilitative Services of the Department of Services for Children, Youth and Their Families, at the Stevenson House Detention Center in Milford, the New Castle County Detention Center and the Ferris School.45
The Department of Correction announces deaths in news releases, posted in its online newsroom from 2016 on, that give the person's name and age, the prison, and the time and place of death.67 The Adult Correction Healthcare Review Committee, nine appointed members placed within the Criminal Justice Council, must review the medical records and autopsies of every person who dies while incarcerated, and it reports once a year to the governor and the General Assembly. State law says the committee is not a public body.8
For the federal Death in Custody Reporting Act, the Criminal Justice Council has the Statistical Analysis Center collect a report on each death from police agencies, the Department of Correction and the Division of Youth Rehabilitative Services, and a quarterly form from each agency that had none. The center asks for the first report within 15 business days of a death and says it searches for deaths that were not reported. It holds that the agencies own the data, and the U.S. Bureau of Justice Assistance does not release identifiable records.9 Senate Bill 291, signed on July 23, 2026, wrote these duties into state law. It requires the medical examiner to mark the death record of anyone who dies in custody, requires the Criminal Justice Council to report each agency's compliance to the governor and the General Assembly by December 1 each year, and has the Department of Justice check those reports. An agency the council finds out of compliance loses certain federal and state grants until it complies.1011
The committee that must review every death in the prisons reports far fewer deaths than the department announces. For January through November 2019, the Adult Correction Healthcare Review Committee reported reviewing 13 deaths, 29 morbidity and mortality reports and nine autopsies.32 For the same months of 2025 it reported two deaths, one mortality review and no autopsies.33 In those months the department announced by name the deaths of at least 16 people in its custody.34 Both reports say, in the same words, that the department may wait more than six months for the autopsy in an uncomplicated case, which keeps the committee from doing its work; the 2025 report adds that when a homicide, an accidental overdose or a crime is suspected, the Division of Forensic Science must get the Department of Justice's approval before it releases the autopsy.3233
The department's news releases do not cover every death. In 2016 it announced eight deaths by name, while it reported 14 deaths that year to the Bureau of Justice Statistics.353 The death of Fred O'Neal III in April 2026 was announced by the Delaware State Police; the department's newsroom has no release about it.296 The list of deaths from 2015 through 2019 that the department released to the UCLA Law Behind Bars Data Project has 65 deaths, five fewer than the department reported to the Bureau of Justice Statistics for those years.363
