To assess the theory that youth homicides in Los Angeles, Calif, are largely attributable to gang involvement in the trafficking or use of drugs.
DESIGN, SETTING, AND PARTICIPANTS: 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.
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.
Our investigation does not support the theory that a substantial proportion of homicides are attributable to gang involvement in narcotics trafficking.
评估一种理论，即加利福尼亚州洛杉矶市的青少年杀人案在很大程度上归因于帮派参与毒品交易或使用。
设计、背景和参与者：首先，我们分析了一个警方数据库中1986年1月1日至1988年8月31日在洛杉矶发生的所有杀人案，以研究帮派活动与毒品使用及交易之间的关联。其次，我们使用警方档案中的详细数据，对洛杉矶中南部一部分杀人案的相同关联进行研究。第三，我们调查了1987年洛杉矶所有杀人案中帮派杀人受害者与受害者可卡因使用情况之间 的关联。最后，我们比较了帮派杀人受害者与其他杀人案受害者的毒品逮捕记录。
帮派动机杀人案比其他杀人案涉及毒品的可能性更小，毒品动机杀人案涉及帮派成员的可能性更小。1987年帮派动机杀人案的受害者比其他杀人案受害者血液中可卡因可检测水平更低。最后，涉及帮派杀人案的年轻受害者与其他受害者相比，有毒品逮捕记录的可能性并无更高。
我们的调查不支持大部分杀人案归因于帮派参与毒品交易这一理论。
