Occupational Homicides of Law Enforcement Officers, 2003-2013: Data From the National Violent Death Reporting System.

INTRODUCTION: Law enforcement officers (LEOs) in the U.S. are at an increased risk for homicide. The purpose of this study is to describe the characteristics of homicides of LEOs in 17 U.S. states participating in the National Violent Death Reporting System. This active surveillance system uses data from death certificates, coroner/medical examiner reports, and law enforcement reports.
METHODS: This study used quantitative and qualitative methods to analyze National Violent Death Reporting System data for 2003-2013. Deaths of LEOs feloniously killed in the line of duty were selected for analysis. LEO homicides and the circumstances preceding or occurring during the incident were characterized. Analyses were conducted October 2015-June 2016.
RESULTS: A total of 128 officer homicides from 121 incidents were identified. Most (93.7%) LEO victims were male, 60.9% were aged 30-49 years (average age, 40.9 years). Approximately 21.9% of LEOs were killed during an ambush, and 19.5% were killed during traffic stops or pursuits. Of the 14.1% of LEOs killed responding to domestic disturbances, most disturbances were intimate partner violence related. More than half (57.0%) of homicides were precipitated by another crime, and of these, 71.2% involved crimes in progress. Most suspects were male. Ninety-one percent of homicides of LEOs were committed with a firearm.
CONCLUSIONS: This information is critical to help describe encounter situations faced by LEOs. The results of this study can be used to help educate and train LEOs on hazards, inform prevention efforts designed to promote LEO safety, and prevent homicide among this population.

Introduction

According to the 2008 Bureau of Justice Statistics' Census of State and Local Law Enforcement Agencies, there are 17,985 law enforcement agencies that employ at least one full-time officer or the equivalent in part-time officers in the U.S., the majority being police officers.[1] State and local law enforcement agencies employed about 1,133,000 people on a full-time basis.[1] Law enforcement is a high-stress occupation[2-5] that involves exposure to potentially dangerous and violent situations such as conducting criminal investigations,[6] responding to crimes in progress,[7] conducting patrols, [6,8] apprehending criminals, managing escalating hostile encounters such as disturbance calls[7] including domestic disturbance calls,[10] working late at night or during early morning hours,[11] pursuing fleeing or speeding motorists,[9] and conducting traffic stops.[7]

Law enforcement officers (LEOs) are exposed to violence, suffering, and death as an inherent part of their profession.[4] As a result of exposure to these situations, LEOs are also at an increased occupational risk for homicide; in 1992-2002, the occupational homicide rate among LEOs in the U.S. was 5.6 per 100,000.[12] This rate ranks fourth, after taxi drivers, liquor store employees, and gas station employees, respectively.[13] According to the Federal Bureau of Investigation's (FBI's) Law Enforcement Officers Killed and Assaulted (LEOKA) Program, from 2005 to 2014, a total of 505 LEOs were feloniously killed in the line of duty.[14]

There is a growing body of literature regarding violence against LEOs.[11,15-18] Previous studies that have examined occupational fatalities among LEOs have focused on homicides and transportation-related fatalities,[12,19] or solely homicides. [8,10] Commonly used databases for these studies include the U.S. Department of Labor's Census of Fatal Occupational Injuries,[20] FBI s LEOKA Reports,[21] and National Law Enforcement Officers Memorial Fund database.[22] Though LEOKA data include written summations, National Violent Death Reporting System (NVDRS) includes narrative data from two sources: coroner/medical examiner reports (CMEs) and law enforcement reports. CME reports provide a different and strong approach to measurement in that the circumstances of death are determined from experts trained to determine the cause of death. The law enforcement reports also provide a detailed understanding of the incident. The narrative data also provide detailed information regarding situational encounters of victim officers, which is an important area of contribution to the literature.

Using data obtained from the NVDRS, the current study describes the occurrence of and circumstances associated with occupational homicide of LEOs in 17 U.S. states. The objective of this analysis is to describe the demographics of LEO homicide victims, describe the detailed circumstances surrounding the deaths of these officers killed in the line of duty, and identify patterns of behavior and the situational context of such deaths. It is hoped that the findings will be used to inform prevention strategies for training of LEOs that promote officer safety and can help to minimize the risk of injury and death.

Methods

The NVDRS is an active, state-based surveillance system that collects information on violent deaths in participating states. The NVDRS case definition for violent deaths includes homicides, suicides, deaths due to legal intervention, deaths of undetermined intent, unintentional firearm deaths, and deaths due to terrorism. The methods of NVDRS have been described previously.[23-27] The system links data from three required sources—death certificates, CME reports, and law enforcement reports—into a single record. The CME reports and law enforcement reports contain narratives with detailed information regarding the violent death and precipitating circumstances. Trained abstractors review these records and abstract the information into variables coded according to standardized Centers for Disease Control and Prevention guidance. The abstractors also create an incident narrative that includes a description of the precipitating circumstances of death. Information is collected on victims (deceased individuals) and limited information is collected on alleged perpetrators (deceased or live suspects).[24] An incident is defined as a single violent death, or multiple violent deaths if the deaths are related and the fatal injuries were inflicted <24 hours apart. The incidents in this analysis were from data submitted by the 17 states participating in NVDRS during the study period: Alaska, Maryland, Massachusetts, New Jersey, Oregon, South Carolina, and Virginia (2003–2013); Colorado, Georgia, North Carolina, Oklahoma, Rhode Island, and Wisconsin (2004–2013); Kentucky, New Mexico, and Utah (2005–2013); and Ohio (2011–2013). Analyses were conducted from December 2015 through June 2016.

Case Identification

Homicides of LEOs were identified by an NVDRS variable designed to specifically capture deaths of LEOs killed in the line of duty. To ensure that all LEO deaths were included, in addition to selecting and reviewing cases where this variable was checked, a text search of the occupation variables in NVDRS, which are based upon data from the U.S. Death Certificate and would include a victim's usual occupation,[28] was conducted. The occupation field was missing or unknown in 8 of 128 (6.3%) incidents. Search terms[a] were also used. Cases identified uniquely by the text search were then reviewed and checked for inclusion or exclusion in the analysis. The text search yielded two additional cases, illustrating the reliability of this NVDRS variable.

For the purposes of this analysis, the term “LEO” can include people who are employed by local, county, state, tribal, or federal entities in occupations such as municipal or county police, constables, state police, highway patrol officers, sheriffs and deputies, marshals, and special agents.[29] The term “line of duty” designates on- or off-duty LEOs acting in an official capacity (i.e., reacting to a situation that would ordinarily fall within the scope of their official duties as an LEO).[29]

Bail bondsmen, private security guards, and emergency responders such as firefighters or emergency medical technicians were excluded from this analysis.

Demographic Characteristics of Law Enforcement Officer Victims

The demographic characteristics of victim LEOs included sex, age, race/ethnicity, history of prior military service, and occupation. The list of occupations was put into general categories: police, law enforcement, sheriff, state trooper, and constable.

Incident Characteristics of Law Enforcement Officer Homicides

Contextual variables such as type of assignment (i.e., if the LEO was on patrol alone), and if the LEO died at the scene were coded from NVDRS narratives based upon definitions developed for the study. Type of location where injured; primary cause of fatal injury (i.e., method used); wound location; and time of day are collected routinely in the NVDRS system and are also presented.

Circumstances/Scenarios of Law Enforcement Officers Killed in the Line of Duty

To identify the proportion of homicides of LEOs that are related to criminal activity, specifically felonies (e.g., robbery or drug trafficking), NVDRS includes information about crimes that precipitated the violent death (e.g., hours to days prior) but that did not occur immediately prior to the LEO death. Thus, NVDRS uses a broader definition of criminal activity than the one used by FBI's Supplementary Homicide Report system. This system only counts felony-related deaths as those that occur while another felony is in progress.[30] An “in-progress crime” is a serious or felony-related crime that was being committed or attempted at the time of the incident. Other precipitating events captured for this analysis included whether the LEO victim used a weapon during the course of the incident; whether an argument or conflict preceded the victim's death; intimate partner violence (IPV)-related circumstances; drug involvement (drug dealing, drug trade, or drug use is suspected to have played a role in precipitating the incident); brawls (mutual physical fights); and random violence.

Coded Circumstances and Encounter Situations

Categories used for coded circumstances and encounter situations were based upon a literature review. To identify patterns of LEO homicides and circumstances, most categories for encounter situations used in this analysis were based largely upon the FBI categories that are used for the LEOKA system.[21] The categories used for this analysis were:

ambush, where an LEO is unexpectedly assaulted as the result of premeditated design by the perpetrator;

arrest, where an LEO is arresting or attempting to arrest an offender either through verbal advisement or through physical contact;

traffic stops or vehicle pursuits;

disturbance calls;

domestic disturbances (breaches of the peace or crimes against persons occurring in a family or among other members of the household resulting in a call for law enforcement to respond); and

IPV-related domestic disturbances. IPV-related domestic disturbances were also counted as domestic disturbances, but this category was also used to determine what proportion of domestic disturbances were IPV-related.

Other categories for encounter situations in this analysis included:

handling/transporting of prisoners;

tactical situations (e.g., serving a search warrant); and

whether the officer was serving a warrant.

More than one encounter situation for a given incident could be coded. Incidents were coded and classified into these categories. Narrative reviews were also conducted to identify and code additional contextual variables such as whether the officer struggled with the suspect, and whether the officer's firearm was used against the officer by the suspect. Narrative review is a method that has been used in previous injury studies,[31,32] including studies of LEO homicides.[8,10]

Suspect Circumstances

The NVDRS collects information as to whether homicide suspects attempted suicide (fatally or non-fatally) after the death of the victim officer. Additional variables for suspects were coded. These variables included whether the suspect was arrested, if the suspect was killed during the incident, whether the incident was directly related to the suspect's mental health problems, whether the suspect used the victim officer's (or another LEO's) service weapon, and whether the suspect was under the influence of drugs or alcohol.

Descriptive analyses were conducted. To code cases, narratives were manually reviewed. Cases were double coded by two reviewers, checked to determine concordance, and re-reviewed. A sample of 10% of cases were re-reviewed to check accuracy. Inconsistencies were resolved through a third coder. All data were analyzed using SAS, version 9.3.

Results

Table 1 displays the demographic characteristics of LEO victims of occupational homicides. In 17 NVDRS states, from 2003 through 2013, there were 128 LEOs killed in occupational homicides in 121 incidents. Overall, 120 (93.7%) were male. The average age for victim officers was 40.9 years (range, 23-82 years). Of those killed, 104 (81.2%) LEO victims were non-Hispanic white, 15 (11.7%) were non-Hispanic black, and 7 (5.5%) were more than one race. Thirty-eight (29.7%) LEO victims ever served in the U.S. Armed Forces. Most (63.3%) were employed by police departments. For some LEOs, the agency of employment was missing, and these victim officers were categorized in the “other law enforcement” category.

Type of assignment, place where the injury occurred, whether the victim LEO died at the scene, primary cause of fatal injury, wound location, location of injury, time of day, and day of week are presented in Table 2. Victim LEOs were working alone in 50 cases (39.1%), but were accompanied by other law enforcement personnel in 56 (43.8%) of cases. Most homicides occurred on highways/ streets/roads or in automobiles (46.1%) and homes/ apartments/yards/driveways (31.3%). Officers died at the scene in 14 (10.9%) of the homicides. However, information as to whether an LEO died at the scene was unavailable or unknown for 40 (31.3%) of the victims. The vast majority of LEO homicides (91.4%) were committed with firearms. Most officers had injuries to the thorax (44.9%) and head (39.8%). Most LEO homicides occurred between the hours of 4:01pm to 12am (35.9%) and 8:01am to 4:00pm (30.5%). The most common day of the week that officers were victims of homicide was Thursday (n=26, 20.3%).

Table 3 displays the encounter scenarios that preceded the homicides. Circumstances that were associated with law enforcement homicides included the LEO homicide being precipitated by another serious crime (e.g., drug dealing, robbery) in 73 (57.0%) cases. Of these 73 homicides, 52 (71.2%) involved a crime in progress. In 31 (24.2%) homicides, the victim used a weapon during the course of the incident (meaning that the LEO fought back). In 14 (10.9%) of the homicides, an argument or conflict was related to the victim's death. A total of six (4.7%) involved drugs; two (1.6%) involved a mutual physical fight; and two (1.6%) involved random violence.

The suspect attempted suicide (or died by suicide) after the death of the victim LEO in 14 (10.9%) cases. The suspect was arrested or taken into custody after the incident in 39 (30.5%) cases. In 29 (22.7%) cases, the suspect was killed during the incident. Mental health issues of suspects were noted in 17 (13.3%) of the cases. In 13 (10.2%) of the cases, the suspect used the victim's service weapon (or another LEO's service weapon) against the LEO. The suspect was under the influence of drugs or alcohol in 11 (8.6%) homicides.

Discussion

This analysis used NVDRS data from 17 states to examine occupational homicides of LEOs. The results add to the body of literature on this subject by providing information regarding LEO victims, the nature of injuries, encounter situations, and circumstances. The results demonstrate the value of the system for collecting information regarding LEO homicides.

Data from NVDRS indicate that the most common precipitating factors in LEO homicides were another crime (57.0%) and another crime in progress (71.2%). This is a common scenario that has been previously documented in the literature, finding that LEO homicides often occur during a crime[21] or when suspects were eluding capture after committing a crime.[33]

One of the most common situational encounters noted in this analysis was ambushes (21.9%). In these situations, LEOs were faced with some of the characteristic circumstances of ambushes: the element of surprise, concealment of the assailant, their intentions or weapon, suddenness of the attack, and a lack of provocation.[34] From 2003 to 2014, ambushes constituted 13%–31% of felonious deaths among LEOs.[35] In 2011, the U.S. Attorney General identified developing approaches to counter ambush-style attacks as a top priority for LEO safety.[36] The information from this analysis can be used to inform such efforts and help law enforcement agencies characterize and prevent ambush attacks.

Traffic stops are another precipitating circumstance noted in this analysis, and according to the Bureau of Justice Statistics, the most common reason for contact with the police is being a driver in a traffic stop.[37] In 2011, an estimated 42% of face-to-face contacts that U.S. residents had with police occurred for this reason.[38] Although traffic stops are relatively common occurrences, they pose a unique risk in that they involve elements of uncertainty and can escalate quickly, resulting in ambushes or pursuits. From 2005 to 2014, a total of 93 LEOs were killed in the U.S. during routine traffic stops.[39] Although some studies have found that homicide deaths among LEOs occur less often during traffic stops,[40] of the precipitating circumstance variables that were coded through reviews of CME and law enforcement narratives, 19.5% of LEO homicides in this study involved traffic stops or pursuits. These results are also consistent with a study using LEOKA data,[8] suggesting that discussions of traffic stops should be an integral part of LEO training in order to decrease assaults and fatal injuries and enhance LEO safety.

Non-domestic disturbance calls were also noted as a precipitating factor with involvement in 15.6% of cases. These calls involved a range of circumstances. Domestic disturbance calls also pose a significant threat to LEO safety[10] and result in more assaults and injuries than any other type of assignment or circumstance. In 2014, according to the FBI, 31% of the 48,315 assaults on LEOs occurred during disturbance calls.[41] In this analysis, domestic disturbances were a precipitating factor in 14.1% of all LEO homicides, which corroborates with studies of LEOKA data that found that domestic disturbances accounted for nearly 14%–15% of officer homicides.[10,42] Kercher et al.[10] found that nearly half of the domestic disturbance calls that resulted in officer homicides were specific to IPV. After a careful review of narratives, this analysis found that of the domestic disturbance calls that resulted in LEO homicides, 72.2% (13/18) were considered IPV-related. The discrepancy may be the result of differences in methods, availability of detailed information, a small sample (i.e., not nationally representative), and the way that IPV-related incidents were captured in NVDR Scoding practices. A study of National Incident-Based Reporting System assault data found that other types of incidents can be just as dangerous as domestic violence incidents; however, the authors stated that future research should investigate whether certain subgroups of domestic violence present a special risk.[18]

The findings in this study are also consistent with other studies that have shown that 90% of homicides of LEOs are committed with fire-arms.[6,8,12] In 10% of cases, the suspect used the officer's service firearm. As firearms contribute to such a large proportion of deaths among LEOs, researchers have suggested that efforts are needed to examine the impact of access to firearms and service weapon “takeaways” and how they affect LEO homicides.[8]

Limitations

Some limitations of NVDRS have been noted previously.[26] First, because this is an analysis of 17 states that participate in the NVDRS, the findings are not nationally representative of all LEO homicides. The goal is to ultimately increase the number of states participating in the NVDRS to include all 50 states, the District of Columbia, and U.S. territories to achieve full national representation.

Second, reports received for the NVDRS system may not fully reflect all information known about an incident, particularly in the case of homicides when data are less readily available while cases are being adjudicated. Third, information regarding suspects' criminal history was not routinely available. Fourth, information on body armor was not available. However, protective factor data are not typically collected by NVDRS because CME and law enforcement narratives typically contain only circumstances associated with risk factors. Fifth, NVDRS does not currently routinely collect information for years on the force, or agency affiliation. These are variables that are often cited in other studies and is something that may be considered for inclusion in future NVDRS web-based software releases. However, it is a strength that NVDRS has a variable that specifically captures LEO homicides and that the information collected includes detailed narratives from CME and law enforcement reports.

Conclusions

Violence against law enforcement takes an adverse toll on individual officers, their families, colleagues, departments, the law enforcement profession in general,[11] and communities. Although the number of LEO homicides decreased in 2014,[43] officers are still at risk of dying violently. The National Occupational Research Agenda Strategic Goal 7, Injuries and Fatalities Due to Criminal Assaults, lists reducing homicides of law enforcement personnel as a strategic goal.[44] Several organizations such as the U.S. Department of Justice and International Association of Chiefs of Police have developed recommendations for improving LEO safety.[45-47] The Final Report of the President's Task Force on 21st Century Policing topic area (pillar) includes officer wellness and safety, and encourages the expansion of efforts to collect and analyze data not only on LEO deaths but also on injuries and “near misses.”[47] Systems such as NVDRS are critical to ongoing surveillance of LEO homicides. The current study affords an opportunity to inform policymakers and individuals involved in training federal, tribal, state, and local law enforcement personnel to help prevent deaths and serious injuries among this population.
