The record files of the Dade County Medical Examiner Department were reviewed and 133 homicide-suicides were identified. Of these, ten (or 7.5%) were female perpetrated. The chart data of these 10 female homicide-suicide perpetrators, chart data of 50 female homicide-suicide victims, and 50 female individual suicides systematically selected as controls were tabulated using a standardized instrument. The results were analyzed for differences using simple statistical methods. The comparisons revealed that female homicide-suicide perpetrators were more likely than female homicide-suicide victims to live in mobile homes, kill their lover or ex-lover, have their crime accidentally discovered, leave a suicide note, kill on a weekend, and be depressed, but are less likely than female homicide-suicide victims to live with a spouse. Additionally, female homicide-suicide perpetrators were more likely than individual female suicides to live in mobile homes but less likely to live alone and to be depressed.
Striations produced on rib cartilages by a knife were conclusively matched with the individual characteristics of the cutting edge of the knife. This was accomplished using Dip-Pak $#x00AE; (cellulose acetate butyratE), Coe-Flex $#X00AE (polysulfide dental impression), and comparison microscopy. An absolute identification was made in which all significant striae matched the individual characteristics of the blade's cutting edge.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
