People Killed: 1
Circumstances: On July 28, 2020, concealed handgun permit holder Mark Nielsen, 56, allegedly shot and killed John Achterkirch, 64, following an argument at Achterkirch’s home. That night, police received a call from Nielsen stating that he had been physically assaulted and had shot his attacker. When police arrived, Achterkirch was found lying on the floor with a gunshot wound to the face. He died a few hours later. Nielsen was placed into custody and taken to the hospital with lacerations to his forehead. Danyelle Shatto, Nielsen’s fiancé and Achterkirch’s niece, was also present at the scene. Shatto told investigators that Achterkirch blamed her and Nielsen for the arrest of Joleigha Johnson ̶ who Achterkirch had recently moved into the home ̶ on an outstanding warrant, and that as a result he would have to evict them from the house. Shatto and Nielsen claimed that Achterkirch had threatened to kill them and had attacked Nielsen, and that Nielsen had acted in self defense. Nielsen carried a gun at all times, even while in the house. On the night of the shooting, he was reportedly armed with a Ruger .380 pistol and Llama .45 pistol. As the investigation continued Nielsen’s story changed over time. He claimed his poor recollection might be the result of alcohol intoxication and marijuana use that night. Nielsen was arrested on suspicion of second degree murder.

People Killed: 1
Circumstances: On April 17, 2012 concealed handgun permit holder Daniel Baker, 30, allegedly shot and killed Nicholas Carpenter, 21, and shot and injured Benjamin Williams, 33, and Joshua Fenderbosch, 29. According to news reports, Baker accompanied Fenderbosch’s girlfriend to the home she shared with Fenderbosch. She told Baker that she and Fenderbosch had been fighting and that she was afraid she’d be assaulted if she went to the home alone. The girlfriend had told a friend that she brought Baker along for protection and that he had a gun, but that he should use it only to injure, not kill. The girlfriend paid Baker with drugs in advance for the protection. When they arrived, Carpenter, who also lived at the home, called Fenderbosch and told him that the two were talking about how she would “get back at him.” Eventually, Fenderbosch and Williams arrived at the home. An argument ensued, and Baker claimed that Fenderbosch and his friends held him down and beat him. He then went into “fight mode to survive,” drawing his gun and shooting the three men. But according to Fenderbosch and Williams, only Baker and Fenderbosch were fighting, Williams and Carpenter were not involved. They claim that Baker opened fire on the two unarmed men and that even after the fight between Fenderbosch and Baker had ended, Baker kept shooting. Williams recalled saying, “Dude, why are you shooting people?” Williams told police that Baker shot Carpenter a second time while he was on the ground, and then turned the gun on him, firing twice. Baker faces charges of first degree murder.
UPDATE: On July 24, 2013, Daniel Baker pleaded “no contest” to charges of criminally negligent homicide and misdemeanor drug possession in the death of Nicholas Carpenter. Baker was sentenced to a four-year deferred sentence on the homicide count and 435 days in jail for drug possession. In May 2013, Baker was acquitted on attempted murder charges for the wounding of Benjamin Williams and Joshua Fenderbosch. The jury hung on the first degree murder charge and Williams accepted the plea deal to avoid another trial and a potential life sentence.

Concealed Handgun Permit Holder: David Lee Noriega CONVICTED
Date: September 16, 2008
People Killed: 1
Circumstances: On September 16, 2008, David Lee Noriega allegedly shot and killed Clay Frank Eldred at 11:00 PM outside a scrap yard where Noriega was employed as a security guard. Noriega said he fired five shots from his AR-15 assault pistol to warn Eldred—who he claimed charged him with a baseball bat—and another unidentified man. Detectives stated, however, that there were no signs Eldred had tried to enter the scrap yard. According to an affidavit, after the shooting Noriega reportedly made comments to a fellow security guard that they needed to move Eldred’s body onto the scrap yard property and “make it look like the guy he shot had a weapon.” The fellow security guard eventually pled guilty to a misdemeanor count of prohibited use of a firearm. Felony charges of accessory to reckless manslaughter and tampering with physical evidence were dismissed as part of a plea agreement. The night of the shooting Noriega was also armed with a 454 caliber handgun and had loaned his fellow security guard a 40 caliber handgun. Noriega, who had a concealed handgun permit, was charged with reckless manslaughter and tampering with physical evidence. On December 31, 2009, Noriega pleaded guilty to criminally negligent homicide.
