Episode notes
Suicide Is A Leading Jail Cause Of Death
- Suicide is one of the leading causes of death in American jails, with almost 900 deaths from 2019–2023 reported by the Marshall Project.
- Risk is highest in the first days after booking even though long-term desperation also matters.
Monitor Vital Signs Immediately
- Use monitoring technology like radar and wristbands to detect breathing and heart-rate changes in the first days of custody.
- Deploy these devices particularly during high-risk early custody periods to trigger medical response.
Jails Function As Default Mental Hospitals
- Jails often hold large numbers of people with mental illness and lack the resources to treat them properly.
- That combination elevates suicide risk when crises go untreated behind bars.
