Domestic Violence Homicides in Utah  Utah Commission on Criminal and Juvenile Justice        INTRODUCTION AND General Precipitating Factors BACKGROUND for Domestic Homicide Domestic violence is a serious issue in Utah A great deal of research has been conducted and across the United States.

Strangulation 1 Factors Influencing Conviction Outcomes Use of a weapon was the best predictor of more severe sentences, controlling for other background and situational factors. As reported above, 101 of the 173 perpetrators of domestic homicide in this time period made it to trial and were ultimately convicted of their crimes. As there was a great deal of variation in sentencing, we examined several background and situational factors and their influence on the sentence that was received. These included perpetrator age and sex, victim age and sex, perpetrator criminal history, and the use of a weapon in the homicide. We were particularly interested in explaining the discrepancy between intimate partner and child homicide convictions. Two of the sentenced perpetrators were Conviction Levels and Counts (N = 99) dropped from the analyses, as their homicides Conviction Code # each involved two victims, one being an intimate Capital Felony 5 8 partner and the other a child, and both received 1st Degree Felony 4 41 capital sentences.

Thus, we performed analyses using both the continuous outcome variable and the dichotomous split described above. The table on the right shows Potential Factors Influencing Conviction Outcome the breakdown on the various important % independent predictors for each of these Category Average 1st/Capital outcome variables.

For weapon use, it did not matter if the weapon was a gun vs. other type (knife, bat, axe, etc.). Interestingly, the perpetrator’s criminal history (total arrests or previous violent arrest) did not have a significant influence on conviction outcome. Apart from these effects in isolation, we were also interested in the most important influences on conviction level. To assess this, a multiple regression analysis was conducted, including perpetrator age and sex, victim age (adult/child) and sex, criminal history (total arrests, violent arrest), and weapon use simultaneously as Weapon Use by Age of Victim for predictors of the outcome continuum variable. In Convicted Homicide Perpetrators this analysis, weapon use was the only Weapon Used Age of Victim No Yes significant independent predictor of conviction level (β = .36, p < .05).

Intimate partner homicides could be related to an argument or jealousy in 9 of the 30 cases; 12 of 16 cases for parent homicides (child abuse is identified as an argument); and 14 of 18 cases for other domestic homicides. One third (65/201, 32.3%) of the homicides recorded in the UVDRS system between 2005 and 2007 were included in our study as domestic violence (DV) related. In the area of special circumstances of the homicides: • Arguments about money were recorded as a circumstance in 7.7% (5) of the DV homicides and in 7.4% (10) of the non-DV homicides. • Jealousy was a circumstance in 15.4% (10) of the DV and in 5.9% (8) of the non-DV homicides. • Other arguments were a circumstance in 38.5% (25) of DV and in 39.7% (54) of the non-DV homicides. • Overall, 53.8% (35/65) of the DV homicides resulted from an argument or jealousy compared to 48.5% (66/136) of the non-DV homicides.

The data obtained from incidents limitations on the data available. This is in Utah appear to be consistent with previous especially true considering our original goal research on domestic violence homicide, based to chronicle many of the risk factors on the data that was available. Homicide in described in previous research. general is a very complex crime, and domestic Unfortunately, the official records that we violence homicide in particular is influenced by were able to access for this report did not many factors related to both the individuals always include the data (or the most involved as well as contextual and relationship appropriate data) to represent some of factors. It is clear from the data presented here these important variables.

For other background factors such as In addition to our attempts to describe further jealousy/controlling behavior, substance details and context of these homicides, we also use/abuse, and personality/mental health, provided information about criminal justice this information is very hard to obtain from outcomes. It was interesting to see that some of official records. The new module of the the differences in background and contextual UDVRS that we described in the last factors between intimate partner and child section coded for jealousy and arguments, homicides helped to explain important but this was limited to only a few years of differences in sentences received for these two our time period. categories of crime. For example, two important differences include the fact that males tend to Such limitations especially apply for some commit the vast majority of intimate partner of the important contextual and relationship homicides (with a corresponding majority of variables that were described. Prior female victims) and that intimate partner domestic violence or child abuse was homicides are much more likely to involve the already addressed above, though it is use of a firearm (easily accessible gun as risk equally (or more) difficult to obtain good factor). These two factors (weapon use and data on factors such as separation or male perpetrator) tended to account for much of estrangement (especially if it was in the the differences in criminal justice outcomes for process of occurring), threats that may the two types of homicide perpetrators have been made, and even access to firearms. Even agency contacts are often difficult to account for, as police do not always fully document domestic violence calls, especially if they do not result in October 30, 2009               Page 34

It is also very difficult to access records from agencies such as child protective services or substance abuse and mental health services. Next Steps Once again, we hope that this report will be of use to both policy makers and those that work with populations at risk for domestic homicide. Aside from the current limitations on the data, digging deeper into incidents of domestic violence homicide reveals important patterns and trends that may be used to prevent future homicides of this type. As for improving future data collection efforts, we have proposed a process involving proxy interviews of victims and perpetrators (see the accompanying short report with this proposal and interview questions) that has been successfully used in some other research on domestic violence homicide. In such a method, individuals who were close to the victim or perpetrator (family, friends, co-workers, etc.) are asked various questions about important dynamics of the relationship, past incidents of violence, substance use, and various services that may have been sought and/or used (including the criminal justice system). While difficult to conduct (and obviously difficult for those interviewed), we feel that such interviews could provide a rich source of data that not only fills in some elements we have been unable to collect, but also provides a different perspective from the official records on other important factors surrounding the homicide incident. In summary, we feel this report provides some important and useful information about domestic violence-related homicide (especially those involving intimate partners and children). We hope to continue and improve upon this process in the future, potentially including data obtain from proxy interviews and other data sources that may become available.
