What are the Reasons Inmates are Dying in County and Municipal Jails?

There are many reasons that inmates die in jails. The Los Angeles County Sheriff’s Department, in the interest of transparency, releases year-by-year information about the causes of in-custody deaths. As of today, 40 deaths are listed as having occurred in a Los Angeles County jail facility in 2025. For each in-custody death, there are columns to show both the manner and means of their death. It can take many months before final autopsy results are completed. Therefore, some of the information is still pending.

The following are the causes of inmate deaths shown on the Los Angeles County list of in-custody deaths for 2025 so far:

This tragic list representing inmate deaths can be read as an alert to all jails. Seeing the frequency of drug-related deaths involving drugs such as fentanyl, methamphetamine, and heroin could lead to better preparedness. Detoxification or detox cells shouldn’t simply be cells where inmates go because they are suffering from withdrawal symptoms. A lack of treatment of those symptoms often means the difference between life and death.

Suicide is overall the leading cause of death in jails, and hanging is the means of death in suicides 85% to 92% of the time. Better training to identify when an inmate may be suicidal is essential. The follow-through is just as important to make sure those who are suicidal don’t have access to anything that can be used to fashion a ligature. In addition, close supervision is the best deterrent to suicide.

Diabetic ketoacidosis, like sepsis, is a red flag that an inmate likely did not receive their necessary medication, and medical neglect may have had a part in the death. The investigation of any death by natural causes should be closely examined to determine whether medical neglect had a part in the tragedy.

Questionable and possibly preventable jail deaths must be investigated thoroughly.
