Deaths in Custody Reporting Program (DCRP) collects quarterly inmate death records from each of the nation's 50 state prison systems, 50 state juvenile correctional authorities, and 3,095 local jails. In addition, the program collects quarterly records of all deaths during the process of arrest by each of the nation's 17,784 state and local law enforcement agencies. These death records include information on the deceased's personal characteristics (age, gender and race/ethnicity), their criminal background (legal status, offense types, length of stay in custody), and details of the death itself (the date, time, location and cause of each death, as well as information on autopsies and medical treatment provided for illnesses/diseases).
