Forensic pathologists often state that homosexual homicides are more violent than those with heterosexual victims. Overkill or wounding far beyond that required to cause death is a frequently used descriptor of these deaths. We quantified the number and extent of injuries between homosexual and heterosexual homicide victims to determine whether one group suffered more violence than the other. This case-control study involved 67 homosexual homicide victims and 195 age, race, and gender-matched heterosexual (control) homicide victims from the Broward County Medical Examiner's Office in Fort Lauderdale, Florida, between 1982 and 1992. The sexual preference of the victims was determined by police and medical examiner investigation. We compared the percentage of cases with multiple causes of death, mean number of injuries/case, and the mean number of different body sites with injuries/case between the two groups. The percentage of cases with multiple causes was 12% (n = 8) and 5% (n = 10) in the homosexual and heterosexual victims, respectively, with no significant statistical difference detected (Fisher exact test, two-tail, p = 0.088). The mean number of fatal sharp (5.4 vs 3.3, p < 0.05), blunt (9.0 vs 6.5, p < 0.05), and total (14.5 vs 6.5, p < 0.001) injuries/case was greater among the homosexual victims than among the heterosexual group. These differences were all statistically significant using the Mann-Whitney rank sum test. The mean number of different body sites with injuries/case was also greater (3.5 vs 2.4, p < 0.001) among the homosexual victims than among the heterosexual group. This difference was statistically significant using the Mann-Whitney rank sum test. Homosexual homicides are more violent than heterosexual homicides when one compares the mean number of injuries (fatal sharp, blunt, and total)/case and the extent of injuries on the body. The mean number of stab wounds wounds/case and percentage of cases with multiple causes of death were also greater among the homosexual group, but the differences were not statistically significant.
法医病理学家常称，与以异性为受害者的凶杀案相比，同性恋凶杀案的暴力程度更高。过度杀戮或造成远超致死所需的伤害是描述这些死亡事件时常用的说法。我们对同性恋和异性恋凶杀案受害者的受伤数量及程度进行了量化，以确定哪一类群体遭受的暴力更多。这项病例对照研究涉及1982年至1992年间来自佛罗里达州劳德代尔堡布劳沃德县法医办公室的67名同性恋凶杀案受害者以及195名年龄、种族和性别匹配的异性恋（对照）凶杀案受害者。受害者的性取向由警方和法医调查确定。我们比较了两组中存在多种死因的案件百分比、平均每例受伤数量以及平均每例不同受伤身体部位的数量。同性恋和异性恋受害者中存在多种死因的案件百分比分别为12%（n = 8）和5%（n = 10），未检测到显著的统计学差异（Fisher精确检验，双侧，p = 0.088）。同性恋受害者每例致命锐器伤（5.4对3.3，p < 0.05）、钝器伤（9.0对6.5，p < 0.05）以及总受伤数（14.5对6.5，p < 0.001）的平均数均高于异性恋组。使用曼-惠特尼秩和检验，这些差异均具有统计学意义。同性恋受害者每例不同受伤身体部位的平均数也高于异性恋组（3.5对2.4，p < 0.001）。使用曼-惠特尼秩和检验，这一差异具有统计学意义。当比较平均每例受伤数量（致命锐器伤、钝器伤和总受伤数）以及身体受伤程度时，同性恋凶杀案比异性恋凶杀案的暴力程度更高。同性恋组每例刺伤数量以及存在多种死因的案件百分比也更高，但差异无统计学意义。
