The Denver Post has compiled a list of officer-involved shootings that have happened since Jan. 1. An officer-involved shooting is one in which either police officers or suspects fire shots and someone is injured or killed. 

December

  • Dec. 31: A gunman who killed a Douglas County sheriff’s deputy and wounded four other law enforcement officers died in a shootout after deputies came to his apartment to investigate a noise complaint. Sheriff Tony Spurlock said the suspect ambushed the officers. The suspect fired at least 100 rounds from a rifle after he barricaded himself inside a bedroom. The deputies were all wearing bulletproof vests but were struck in unprotected parts of their bodies, Spurlock said. Deputy Zackari Parrish, 29, was killed. Deputies Mike Doyle, Taylor Davis and Jeffrey Pelle were wounded. Castle Rock police officer Tom O’Donnell also was injured. Two people in adjacent apartments also received non-life threatening injuries.
  • Dec. 31: A Weld County sheriff’s deputy shot an armed suspect after a chase. The deputy was working a DUI shift at 2:41 a.m. and observed a vehicle speeding on Colorado 52 and College Avenue in Fort Lupton. When the driver refused to stop, the deputy gave chase. The sheriff’s office said the suspect was armed with a handgun. The deputy was not wounded. The suspect’s condition was not released. On Feb. 28, Weld County District Attorney Michael Rourke issued a letter saying Deputy Holcomb Nicholson was justified in shooting 54-year-old Michael Nash after a car chase. Rourke did not not release any other details of the investigation, citing pending litigation as the reason. Nash faces charges of felony menacing, felony vehicular eluding, driving under the influence, prohibited use of a weapon and harassment in connection with the incident, said Krista Henery, a spokeswoman for the district attorney.The harassment charge stems from a fight Nash allegedly had with a woman on the same night, according to court documents.
  • Dec. 24: Castle Rock police officers shot a suicidal suspect. The suspect had a gun, which forced officers to fire. The suspect’s injuries were not life-threatening, police said.
  • Dec. 21: Greeley police officers shoot, kill man suspected of stealing a car. The Weld County Sheriff’s office said Greeley police found the stolen red 2018 Chevy Cruze in a ditch in west Evans. When officers talked to a bystander who had offered to help get the vehicle out of the ditch, they learned Jose Angel Aguero Jr., 26, was in the man’s truck. When police tried to talk to Aguero, he ran. Officers tried to stop him using non-lethal bean bag rounds. When Aguero allegedly pulled a gun, the officers shot him. He was pronounced dead on the scene.
  • Dec. 13: Northglenn police officers shoot at two suspects in stolen car as it accelerates towards them, killing one and wounding the other.
  • Dec. 7: Adams County deputy shoots, kills man after altercation with domestic violence suspect. The mother of Kyler “KyKy” Grabbingbear said the deputy should have used his Taser to control her unarmed son, who panicked and ran when he saw a law enforcement officer because he was wanted on a minor crime.
  • Dec. 2: A Colorado Springs police officer shot and killed a man. Christopher Louis Willard, 33, died after he resisted arrest and brandished a BB pistol, the El Paso County Sheriff’s Office said. Two officers tried to arrest Willard on a misdemeanor theft charge.

November

October

  • Oct. 29: Multiple Arapahoe county sheriff’s deputies shot a retired deputy in the parking lot of the sheriff’s department after he pointed a gun at an on-duty officer. Mark Bidon, 50, was shot by multiple deputies around 9:45 p.m., after he backed a vehicle into the exit of the Arapahoe County Sheriff’s Department at 13101 E. Broncos Parkway in Centennial.
  • Oct. 28: Greeley officers fatally shot a man who had backed into a police vehicle and brandished a handgun out of the driver’s side window during an 8-minute chase. Danny Sanchez, 40, had warrants for a parole violation for escape out of the Department of Corrections, a felony warrant out of Larimer County for menacing and previous offender in possession of a weapon, and driving despite losing his license for previous DUI arrests. On Jan. 2, 2018, the Weld District Attorney’s Office issued a report clearing the officers in the shooting. The DA’s office also determined the weapon Sanchez brandished was a realistic-looking BB gun, but that it was unrealistic for officers to be able to make that determination.
  • Oct. 11: A Las Animas County Sheriff’s deputy fatally shot a man who attacked the officer when he responded to a report of a backyard fire. Deputies encountered Kristian Martinez  outside the home. Martinez attempted to flee and when the deputy tried to restrain him, he attacked the deputy and was fatally shot.
  • Oct. 6:  A Colorado State Patrol trooper shot and killed a man in Jefferson County after a chase. A pickup truck driver, who had been fleeing the trooper, lost control and drove off the road. Shots were fired and the driver was declared dead at the scene. The trooper was not injured.
  • Oct. 1: Fort Collins police responding to a report of a suspicious circumstance  at a hotel shot and killed George Randall Newman. None of the officers will face charges, according to a letter from District Attorney Clifford Riedel. Newman had fired a gun through the floor of his hotel room, and the shot went through the roof of the room below. Officers called Newman’s hotel room phone, but he didn’t answer. The officers soon determined that a 3-year-old girl was in the room with Newman. Concerned for the girl’s safety and the safety of others, three officers approached the door of the room and knocked. Initially, there was no answer. After a second knock, Newman opened the door armed with a sawed-off shotgun, according to the DA’s letter. Commands were yelled at Newman to drop the weapon and show his hands. Newman did not comply, according to the letter.


September

  • Sept. 27: Adams County sheriff’s deputies wounded a suicidal man who fired at least one shot at them. On Feb. 7, 2018, 17th Judicial District Attorney Dave Young announced criminal charges would not be filed against the three deputies who wounded the man after the shootout at his home. The wounded man, Troy Coen, told investigators he had decided he did not want to live anymore and had hoped the deputies would kill him. Instead, Coen was wounded in the chest and shoulder but survived. He faces four counts of attempted first-degree murder, four counts of attempted first-degree assault and three counts of menacing. The officers cleared of wrongdoing are Sgt. Chris Eye, Senior Deputy Dustin Ball and Deputy Lance Kestel, according to a letter Young addressed to Adams County Sheriff Michael McIntosh. The deputies were called to Coen’s neighborhood after a resident reported that a man in a red pickup truck had pointed a gun at her husband. The resident told police they suspected it was their neighbor Coen, and the red pickup was parked in Coen’s driveway. Coen, 55, later told police he was angry at the neighbors because he suspected their son had stolen marijuana plants from his backyard, the DA’s letter said.
  • Sept. 22: An Adams County sheriff’s deputy fatally shot a man following an altercation near the Mile High Flea Market at East 88th Avenue and Brighton Road.
  • Sept. 21: A Jefferson County sheriff’s deputy fatally shot a driver during a confrontation in a parking lot. The incident unfolded after the sheriff’s office received reports of a driver speeding on C-470 and passing cars on the shoulder of the highway. A deputy discovered the unoccupied car at an O’Reilly’s Auto Parts store, 8134 S. Kipling Pkwy. When the suspect exited the store, a confrontation ensued between the deputy and the suspect. The deputy fired his weapon, hitting and killing Austin Dunsmore, 25.
  • Sept. 19: An investigation by the 4th Judicial District Attorney’s Office determined Fountain police officers and El Paso County deputies were justified in shooting a driver who led them on a high-speed chase and repeatedly rammed their vehicles. The driver, Robert William Zupko Jr., was wounded but has since recovered and faces charges that include attempted first-degree murder with extreme indifference.
  • Sept. 8: A car theft suspect was injured when he was shot in the face after he reportedly drove toward a Denver police officer while pointing a gun. Denver District Attorney Beth McCann ruled officer Sergey Gurevich was justified in shooting Sergio Casimiro-Mejia. She concluded that Casimiro-Mejia had placed Gurevich in “imminent, life-threatening peril.” McCann said the officer’s body camera footage “demonstrates how well he handled a very scary and tense situation.”Casimiro-Mejia was later charged with first-degree assault on a peace officer, menacing, motor vehicle theft, possession of a weapon by a previous offender and possession of burglary tools.

August

July

June

  • June 30: A Larimer County deputy shot Chet Knuppel in the chest as he was fleeing after crashing a stolen vehicle in a field near Colorado 392 and Larimer County Road 9. Knuppel died later at a hospital of a single gunshot wound to the chest. The deputy was cleared by Larimer County District Attorney Cliff Riedel. Riedel’s report outlines the chaos that led to up to the shooting — Knuppel had reportedly crashed a car stolen from his parents and then attempted to carjack another vehicle from an elderly couple by threatening to shoot them and indicating he had a gun in his rear waistband. When officers arrived they were told about threats Knuppel had made about having a gun. Knuppel ran into a field and as deputies chased him, he turned toward them and was shot.
  • June 30: Westminster police shot and killed Brett Rodriguez, 33, as they tried to arrest him. Officers were in the area looking for a suspect wanted on warrants when they saw the man who was also wanted on warrants. Police said he ran to a car in an attempt to flee and displayed a weapon when officers approached. In a letter clearing the two officers, 17th Judicial District Attorney Dave Young wrote the officers feared for their lives when they saw Rodriquez begin to pull a gun from his waistband.
  • June 30: Police shot and killed Stephanie Lopez, 32, and critically injured a second woman following a carjacking and high-speed chase that traversed Littleton, Englewood and Denver before police stopped the alleged robbers. No officers were struck by bullets in the early morning shootout. Lopez was pronounced dead at the scene and the other woman was hospitalized in critical condition. On Feb. 7, 2018, Denver District Attorney Beth McCann announced that three Littleton Police Department officers and an Englewood Police Department officer were justified in shooting the women. Littleton officers Anthony Guzman, Luke McGrath and Joseph Carns and Englewood officer Brian Martinez knew the car’s occupants had been involved in an earlier carjacking where shots had been fired, McCann wrote in a letter to the chiefs of each department. The driver, Marta Sanchez, then led police on a high-speed chase where she ran red lights and nearly hit a motorcycle as she tried to elude police. Each time officers stopped the car, Sanchez would drive toward them and race off, the letter said. Officers shot at the car 44 times on three occasions before the chase ended. McCann’s analysis also determined that Guzman had used deadly force when he hit the suspect vehicle with his patrol SUV as it made a left turn. “With each subsequent use of force, the suspect vehicle’s continued efforts to escape from police demonstrated a brazenness that justified the officers’ fears that the suspects posed a significant risk of danger not only to the officers but to the public at large,” McCann wrote. Sanchez, 26, was shot multiple times and became a paraplegic because of her injuries. The female passenger, Stephanie Lopez, 32, died at the scene from a gunshot wound to her head, the letter said. Toxicology tests found that Lopez had methamphetamine, marijuana and alcohol in her system. Sanchez had taken methamphetamine and marijuana, the letter said. Both women were wanted by police — Sanchez on three arrest warrants and Lopez for a parole violation from the Colorado Department of Corrections, the letter said. Inside the wrecked car, police found a loaded .38-caliber weapon in a purse, a large knife, 115 grams of meth and 16.75  grams of powder ibuprofen along with needles and a scale, the letter said. No one in the car fired shots at police.
  • June 18: A 31-year-old man was injured in a shootout with Denver police following a car chase from Montbello to Aurora. Keith A. Roberts was convicted in January, 2018, of two counts of first-degree assault, six counts of felony menacing, three counts of possession of a weapon by a previous offender, two counts of vehicular eluding, one count of reckless driving and one count of possession of a controlled substance. On April 3, 2018, Roberts was sentenced to 45 years in prison.
  • June 9: Hector Santana-Arreola, 39, was injured after he pulled a knife on Immigration and Customs Enforcement agents before one agent shot him, grazing his head. Santana-Arreola, who was wanted on two outstanding warrants and is a previously deported felon, suffered a superficial wound. He faces charges of first-degree assault. Denver District Attorney Beth McCann cleared Rueben Coray, an Immigration and Customs Enforcement officer, of criminal wrong-doing. Coray was within arm’s reach of Santana-Arreola when he brandished the utility knife and could have seriously injured the officer.
  • June 8: Stephen Rich, 48, died in an exchange of gunfire with four Loveland police officers. Eighth Judicial District Attorney Clifford E. Riedel determined Rich gave the officers no choice but to fire their weapons in self-defense after he fired two shots at them. Footage from a police car’s camera showed that less than 2 seconds elapsed between Rich’s first shot and the officers returning fire. One of the officers was on patrol when he saw a motorcyclist make an improper turn. The officer followed the motorcycle and activated his lights after seeing the motorcyclist make several other traffic violations. The officer ended the pursuit after the motorcyclist ran a red light. About 13 minutes after the officer first saw the motorcyclist, a motorist called to report a motorcyclist had struck his car and that he had followed the motorcyclist to a residence. The four officers responded to the scene. The officers, the 911 caller and a friend of his all said the motorcyclist, who later was identified as Rich, walked away. Rich then reached behind his back and pulled out a Glock semi-automatic pistol and fired two shots.

May

  • May 31: James Daniel Hill, 17, was shot and killed after a high-speed chase with Arapahoe County deputies. The deputies spotted the car, which had been reported stolen in an armed carjacking. During the pursuit, the car became immobilized in Centennial and five suspects fled the vehicle. A deputy ran after Hill, who deputies said displayed a gun. The District Attorney’s Office for the 18th Judicial District determined Deputy Robert Knudson justifiably used deadly force to protect the public and other officers.
  • May 20: Brendan Gerwing, 23, was charged with two counts of attempted first-degree murder and three counts of first-degree assault after a shootout with Denver police officers who had been called to help a suicidal person. Gerwing allegedly shot a police officer who tried to subdue him with a stun gun. Gerwing was then shot by another police officer. The officer was treated for a shattered fibula in his right leg. It was the second time in eight months that police were called after Gerwing was reported to be suicidal. On Sept. 29, Denver’s district attorney  cleared the Denver police officer involved in the shooting. According to a letter issued by district attorney Beth McCann, the wounding of Gerwing by Denver Police Sgt. Chad Kendall after Gerwing shot officer John Allred was legally justified. Her review included viewing footage from body cameras worn by the five officers who responded to the call.
  • May 12: A Douglas County sheriff’s deputy had a split second to react when he suddenly came face to face with a man holding an assault rifle near an SUV stopped along a suburban roadway. The sheriff’s office released the video of Deputy Brad Proux, a six-year veteran, approaching the vehicle and suddenly encountering the driver, who stood with an assault rifle in his hands. Proux shot Deyon Marcus Rivas-Maestas, 25, who has been charged with first-degree assault of a peace officer. The 18th Judicial District Attorney’s Office determined Proulx was justified in shooting and wounding Rivas-Maestas, according to a letter written by Jacob Edson, chief deputy district attorney to Douglas County Sheriff Tony Spurlock. “In this circumstance, Deputy Proulx reasonably believed unlawful physical and deadly force was about to be applied upon him by Rivas-Maestas,” the letter said. “Deputy Proulx recognized Rivas-Maestas possessed an AR-15 rifle, more powerful than the service weapon he was carrying. Deputy Proulx reasonably believed Rivas-Maestas would or could use the rifle not only in a striking motion, but perhaps to fire at him.”
  • May 9: Westminster police shot and killed an armed fugitive after he allegedly stole a car and then barricaded himself in an apartment and shot a police officer. Gunshots were exchanged when officers entered the residence. The suspect shot and injured an officer and a police dog also was injured and taken to an emergency veterinarian for treatment. Police officers shot and killed the fugitive, who was pronounced dead at the scene.

  • March 14: Alexander Meltz, 18, was shot and killed in Westminster by police officers assigned to an interagency, Denver-area auto-theft task force. Metz was pronounced dead at the scene of the shootout at Cotton Creek Park north of Legacy Ridge Golf Course. Investigators say Meltz, who was connected to a stolen vehicle, was shot after he brandished and pointed a weapon at officers who confronted him. Authorities have declined to say what kind of weapon he was holding. There were four officers involved in the shooting, including two Colorado State Patrol troopers, an officer from Wheat Ridge and an officer from Lakewood. All four fired at Meltz.
  • March 3: Michael Kocher, 32, was shot and killed by an officer during a standoff with Englewood police. Kochner died of a gunshot wound to his torso.
