title: Gangs, drugs, and homicide in Los Angeles.
abstract: OBJECTIVE
  To assess the theory that youth homicides in Los Angeles, Calif, are largely attributable to gang involvement in the trafficking or use of drugs.
  
  
  METHODS
  First, we analyzed all homicides in a police database that occurred in Los Angeles between January 1, 1986, and August 31, 1988, to examine the association between gang activity and narcotic use and trafficking. Second, we used detailed data from police files to examine the same associations for a subset of homicides in south central Los Angeles. Third, we investigated the association between gang homicide victimization and victim cocaine use for all 1987 Los Angeles homicides. Finally, we compared narcotics arrest histories for gang homicide victims with histories for other homicide victims.
  
  
  RESULTS
  Gang-motivated homicides were less likely than other homicides to involve narcotics, and narcotics-motivated homicides were less likely to involve a gang member. Victims of gang-motivated homicides in 1987 were less likely than other homicide victims to have detectable levels of blood cocaine. Finally, young victims of gang-involved homicide were no more likely to have a history of narcotics arrests than other victims.
  
  
  CONCLUSIONS
  Our investigation does not support the theory that a substantial proportion of homicides are attributable to gang involvement in narcotics trafficking.
