Researchers used surveys of jail and corrections officials, medical examiners, and a newspaper clipping service. Analysis of the data yielded a hypothetical victim profile: a 22-year-old single white male, arrested for public intoxication as the only offense. The typical victim is under the influence of alcohol upon incarceration in an urban county jail where he is placed in isolation for his own protection and surveillance. However, less than 3 hours after incarceration, the hypothetical victim is dead, having hanged himself with material from his bed in the jail cell. The incident takes place on a Saturday night in September between the hours of midnight and 1:00 a.m. Jail staff finds the victim within 15 minutes of the hanging. Jail records indicate that the victim did not have a history of mental illness or previous suicide attempts. The statistics from which the above profile emerged show 60 percent of the suicide victims under the influence of alcohol or another drug at the time of incarceration; two out of every three inmates who committed suicide were being held in isolation. Over 50 percent of the suicide victims were dead within the first 24 hours of incarceration; 27 percent died within the first 3 hours. The report recommends that jailers be alert for inmates whose characteristics fall within the victim profile. These inmates should receive special attention during initial incarceration, especially the first 3 hours, and isolation should not be used for inmates exhibiting suicidal behavior. Cosmetic precautions to prevent suicides at a facility--e.g. barless windows and television monitors--should not supplant the more necessary human interaction. Public officials and legislators should broaden the use of pretrial release, decriminalize public intoxication, and provide programs of support following detoxification. Jail suicide reporting should be improved. Tabular data and 51 references are included. (Author summary modified)
