Law Enforcement Officers Shot to Death in 2013

by Everytown for Gun Safety and the Major Cities Chiefs Association

May 14, 2015

In 2013, there were 25 incidents nationwide in which law enforcement officers were killed with guns that were not their own. An analysis of FBI data shows that at least thirteen of these incidents — 52 percent — were committed by individuals who were likely barred under state or federal law from either purchasing or possessing firearms.

To conduct the analysis, researchers obtained the FBI’s Law Enforcement Officers Killed and Assaulted (LEOKA) database covering felonious deaths of law enforcement and updated it with additional incidents from press reports. For those incidents in which an officer was killed with a firearm that was not his or her own, the researchers identified the assailant and then examined state and federal criminal records as well as contemporaneous newspaper accounts to determine if the individual was prohibited by law from either purchasing or possessing firearms. Gun violence is a persistent threat to law enforcement — and preliminary FBI data indicates that the number of officers killed feloniously with firearms rose 77 percent since 2013.Federal Bureau of Investigation, May 11, 2015, “FBI Releases 2014 Preliminary Statistics for Law Enforcement Officers Killed in the Line of Duty,”

While no single policy can completely ensure officers’ safety, strong gun laws that reduce the
flow of guns to criminals can help save lives. Loopholes in our current laws make it all too easy for dangerous people who are prohibited from possessing guns to dodge a background check and buy a gun from an unlicensed seller. Expanding background checks to cover all gun sales — including those online — will protect cops. In states that require background checks for unlicensed sales of handguns, police are 48 percent less likely to be killed with handguns.Everytown for Gun Safety, State Background Check Requirements and Rates of Firearm Homicide Against Law Enforcement, January 2015, available at



January 26 | St. Mary Parish, Louisiana: Using a shotgun, Wilbert Thibodeaux, 48, shot and killed Sergeant Frederick Albert Riggenbach and shot and wounded Deputies Matthew Strickland and Jason Javier. The officers were responding to reports of a man with a long gun walking on a road near a casino and acting suspiciously; as officers approached him, Thibodeaux opened fire. At the time of the incident he was wanted on felony assault charges in Texas, which prohibited him from purchasing, receiving, or transporting firearms.John DeSantis, “Cop-Slay Suspect Granted ‘Get out of Jail Free’ Card,” The Houma Times, February 13, 2013,

February 28 | St. Lucie County, Florida: Eriese Tisdale, 25, shot and killed Sergeant Gary Morales of the St. Lucie County Sheriff’s Office after the officer pulled him over for speeding; when Morales approached Tisdale’s vehicle, Tisdale opened fire, killing the officer. In 2010, Tisdale was convicted of felony drug possession, which prohibited him from possessing firearms.Melissa Holsman, “Eriese Tisdale: Trial Set for End of May for Suspected Killer in Sgt. Morales Slaying,” Scripps Treasure Coast Newspapers, January 7, 2015,

March 19 | Monument, Colorado: Evan Ebel, 28, rang the doorbell of Thomas Lynn Clements, the Executive Director of the Colorado Department of Corrections. As Clements opened the door, Ebel opened fire on Clements, killing him. Ebel was a member of a white supremacist prison gang that targeted Clements and other prison officials. His prior criminal record prohibited him from possessing firearms: On February 11, 2005, he was convicted of robbery, assault, and menacing in Jefferson County and was sentenced to eight years in prison. He was sentenced to an additional four years in 2007 for an assault on a correctional officer in Fremont County.Michael Roberts, “Evan Ebel’s Feces-Smeared Prison Records and Straw Purchase Controversy,” Denver Westword, March 29, 2013, Case No. 04CR3622 (Adams County, CO). Ebel was out on parole at the time of Clements’ murder, and obtained the 9mm Smith & Wesson semi-automatic handgun he used in the shooting from a childhood friend who straw-purchased it at a licensed gun dealer two weeks prior to the murder.Arkadi Gerney, “How a Straw Purchaser Allegedly Enabled the Colorado Prison Chief’s Murder,” ThinkProgress, March 29, 2013,

April 3 | Mingo County, West Virginia: Tennis Melvin Maynard, 37, ambushed Mingo County Sheriff Eugene Crum while he sat in his marked vehicle in a parking lot eating lunch, shooting and killing him. Maynard had been institutionalized two times on account of severe mental illness, and as a consequence was prohibited from possessing firearms. He was able to pass a background check and buy a firearm in December 2010 because the state had delayed in submitting his mental health records to the FBI database of prohibited buyers. Later, once his records had been submitted, the background check system blocked him from two attempts to buy additional firearms.Kate White, “Judge: Accused Killer of Mingo County Sheriff Mentally Incompetent,” The Charleston Gazette, January 15, 2015,

April 18 | Boston, Massachusetts: Tamerlan Tsarnaev, 26, and his brother Dzhokhar Tsarnaev, 19, shot and killed patrol officer Sean Collier, 27, with a handgun during the aftermath of the Boston Marathon terrorist attack, which they were also charged with perpetrating. Dzhokhar could not have legally possessed a handgun in the state of Massachusetts due to his age, and Tamerlan did not have a valid Massachusetts handgun permit. In 2011, a Maine resident legally purchased the Ruger P95 used in the crime along with multiple other handguns at a Cabela’s store in Maine, and then passed the gun to a Portland gang member in an unlicensed transfer, from whom Tsarnaev likely obtained the gun.Gavin Aronsen, “What We Know About the Tsarnaev Brothers’ Guns,” Mother Jones, April 23, 2013,
