ALCOHOL, DRUGS AND MURDER - A STUDY OF CONVICTED HOMICIDE OFFENDERS

Data on 1,887 convicted homicide offenders were examined to discern the relationships between alcohol and/or drug use and murder. Information obtained through confidential interviews at state prisons and local jails provided demographics and information on drinking and drug use immediately before the crime and relevant data on the offenders' typical drinking style. About 50 percent of the offenders were under the influence of alcohol at the time of the crime, similar to the rate found by other studies. Substance use was more prevalent than nonuse before the homicide: 36 percent used alcohol only, 13 percent used both alcohol and drugs, 7 percent used drugs only, and 43 percent did not use either. A heavier style of drinking is much more prevalent among homicide offenders than in the general population. Blacks showed the least involvement with alcohol before homicide. A direct role for alcohol is indicated by the finding that homicides were associated with a heavier than usual episode of drinking and the large mean alcohol consumption contiguous to the crime (9.3 ounces of alcohol or about 18 drinks). Evidence also indicates that a unique relationship existed between drug use and homicide. © 1990.
