The Ada County Critical Incident Task Force investigation into the events that led to an officer-involved shooting on June 28, 2016 is complete. The Canyon County Prosecuting Attorney has determined that the involved officers’ use of force was reasonable. As part of standard procedure, an internal review by the Boise Police Department is also underway.
“Last June, Officers Jason Green, Joe Martinez, and many others acted with courage to protect the public and themselves in a life-threatening situation,” said Boise Police Chief William Bones. “Incidents like this highlight the difficult circumstances our officers encounter and the Boise Police Department values a fair and transparent investigation into their actions. We appreciate the CITF and the Canyon County Prosecuting Attorney’s Office for their complete and thorough investigation.”
On June 28, 2016, at approximately 23:42, Boise dispatch received a report of a shooting that had just occurred in the vicinity of W. Bridlewood Circle in Boise. Fifty-three-year-old Alan Amundson drove to the home of the woman he had been dating after she broke up with him. There, Amundson argued with the woman and attempted to strangle her. When her teenage son came to her defense, Amundson shot him in the chest and arm with a .40 caliber handgun. Amundson then battered the woman’s teenage daughter. She and her children managed to flee from the residence and find refuge in the home of a neighbor, who called for police and emergency medical service. Amundson returned to his truck parked on the street in front of his victims’ home, retrieved a rifle, and began firing rounds into adjacent houses.
Boise Police Officer McCarthy was the first to arrive on scene. While Officer McCarthy was making his initial observations of the scene from behind an RV parked near Bridlewood and Glenwood, Amundson fired his rifle, shooting Officer McCarthy through the RV. The bullet penetrated Officer McCarthy’s clothing and partway through his bulletproof vest. The extent of Officer McCarthy’s injury could not be determined until he was transported to the hospital for treatment. Amundson then shot at Officer Steve Martinez, who was the next officer to arrive at the scene. The bullet struck the passenger side taillight of Officer Martinez’s police car.
Responding officers yelled commands for Amundson to show his hands, but there was no compliance. It was dark outside and officers were not able to initially determine if Amundson was lying in wait partially concealed by his truck or just not complying with their commands. Amundson fired more rounds, including one that was later determined to be self-inflicted and fatal.
Approximately two minutes after Amundson’s last shot was fired, Officers Joe Martinez and Jason Green advanced towards Amundson’s position and each fired a shot at Amundson. Officer Green fired a .223 round from his patrol rifle and Officer Joe Martinez fired a .45 caliber round from his service pistol. One of the rounds penetrated Amundson’s right arm. Officers then approached Amundson and found that he was deceased with an apparent self-inflicted gunshot to his head. Officers then located the victims and rendered assistance. The victims were treated and recovered.
The Ada County CITF conducted an investigation, locating twenty-six spent .223 caliber rifle casings and six spent .308 caliber rifle casings with head-stamps different from those rounds used by the police officers. All were likely fired by Amundson. An autopsy was conducted by Dr. Garrison in the Ada County Coroner’s Office. Dr. Garrison determined the cause of death was a self-inflicted gunshot wound to the head.
