Despite the importance of intimate partner violence (IPV) and homicide research to women's health and safety, much remains unknown about risk factors for intimate partner homicide (IPH). This article presents the Arizona Intimate Partner Homicide Study, pilot research that is being conducted in one U.S. state to update and expand on risk factors for IPH. In the context of presenting this study, we summarize the literature on data collection techniques, various marginalized and under researched populations, and the importance of gathering data about the victim-offender relationship and situational IPH risk factors. Additional research is needed to update risk factors for IPH to account for changes in technology and to examine differential risk across diverse populations. Local, community based data collection strategies are likely to provide more comprehensive and nuanced insight into IPH; though, to understand risk factors among marginalized populations, it may be necessary to increase sample size through a national strategy. Although not a panacea, we present this ongoing research as a model for other states to emulate and improve upon, in the hopes of developing more comprehensive data examining risk for IPH among victims of IPV.Keywords Intimate partner violence . Intimate partner homicide . Risk assessment In the United States, intimate partner homicide (IPH) accounts for one-fifth of homicides overall (Jack et al. 2018). IPH is a gendered crime; approximately 40-50% of murdered women are killed by a current or former intimate partner compared to only 5-8% of male homicide victims (Fridel and Fox 2019;Jack et al. 2018). Although the percent of homicides of men that were committed by an intimate partner decreased by 53% between 1980 and 2008, the percent of homicides of women committed by an intimate partner increased by 5% during this same period (Cooper and Smith 2011). Women with marginalized identities are at particular risk of femicide (the killing of

Purpose Given that formal training on autism is still a relatively infrequent occurrence for police officers, the objective of this study is to expose and describe the formal and informal, nonorganizationally based means police officers receive on-the-job training regarding interactions with autistic individuals.Design/methodology/approach Using personal networks and snowball sampling, the authors interviewed 19 police officers from multiple US police departments who reported having known contact with an autistic individual while on duty. Interviews were transcribed and coded to identify themes describing formal training and informal means to learn about autistic persons during interactions.Findings The authors find that many officers received formal training on mental health, though few received specific training about autism. Most commonly, officers with a personal connection to autism (e.g. a child or loved one), passed down information and techniques to other officers on how to have positive encounters with autistic individuals. Officers also passed along field knowledge of known autistic individuals in patrol areas/beats to help others have positive interactions. Lastly, community members often assisted officers by sharing information about find where an individual may be located, may live or known personal characteristics/preferences.Originality/value Scholars examining police contact with autistic individuals infrequently detail the point of view and needs of officers in successfully interacting with this population. This work adds to this growing discussion by exposing how officers use personal experience, informal training and community members’ assistance as a stopgap for their general lack of training on how to interact with autistic individuals successfully and positively.

This study examines the covariates of weapon choice in homicide incidents. Two research questions are examined. The first research question is: what variables influence the use of a particular type of weapon in a homicide? The second research question asks: how does the method of weapon retrieval, or lack thereof, affect the choice of weapon? The findings suggest that firearms are more likely to be on the offender’s person and carried to the incident scene relative to other weapon types. In addition, the use of specific types of weapons is conditioned by the demographic and lifestyle characteristics of victims and offenders.
