A 21-year-old Kootenai man remains free following a deadly shooting Sunday evening at his West 1st Street residence after the Bonner County Sheriff’s Office determined Idaho’s Castle Doctrine justified his use of lethal force against an intruder who had physically attacked him.
Shawn Webster shot and killed 50-year-old Jason Leroy Sparks on July 19 after Sparks entered the home without invitation and, according to investigators, physically assaulted Webster in his bedroom. No arrest has been made, though the Bonner County Prosecutor’s Office will conduct an independent investigation to assess whether criminal charges are warranted.
What Happened Inside the Kootenai Home
Witnesses reported hearing yelling at the residence at approximately 6:57 p.m. Law enforcement was notified shortly after, around 7 p.m. Officers arrived to find Sparks dead in the bedroom with a single gunshot wound to the neck.
Investigators pieced together the following sequence of events: Sparks, the ex-husband of Ashley Sparks, had been at the home working on her vehicle. Webster and Ashley Sparks reside together at the West 1st Street address. According to the Sheriff’s Office, Jason Sparks entered the residence without being asked inside and began acting aggressively.
Webster, who had previously received threats from Sparks, withdrew to his bedroom in an attempt to remove himself from the confrontation. Sparks followed him. The situation escalated rapidly when Sparks grabbed Webster by the throat and began lifting him off the ground.
The Sheriff’s Office described what happened next: “Shawn retreated to his bedroom and armed himself with a pistol. Jason followed Shawn into the bedroom, grabbed him by the throat and started to lift him off the ground. In response, Shawn fired a single shot into Jason’s neck, stopping the attack and ultimately killing Jason.”
Sparks was pronounced dead at the scene.
Castle Doctrine Shields Webster From Arrest
The Bonner County Sheriff’s Office cited Idaho’s Castle Doctrine as the legal basis for declining to arrest Webster. Under Idaho law, a person has the right to use deadly force to defend themselves against an unlawful intruder in their home, place of work, or occupied vehicle — and critically, there is no requirement to attempt to flee before doing so.
The Sheriff’s Office stated directly: “Idaho’s Castle Doctrine permits the use of deadly force against an unlawful intruder in your home, workplace, or occupied vehicle.”
Idaho’s Castle Doctrine removes the duty to retreat that exists under the laws of some other states. When an intruder unlawfully enters a protected space and poses an imminent threat to the occupant, Idaho law recognizes the occupant’s right to defend themselves with lethal force without first attempting to escape. In this case, investigators determined that Sparks was the unlawful aggressor, that Webster had no obligation to flee further once inside his own bedroom, and that the physical assault — being choked and lifted from the ground — constituted an imminent threat to Webster’s life or safety.
The prior threats Webster had received from Sparks also factored into the investigation, providing context for Webster’s decision to arm himself once Sparks entered the home and began acting aggressively.
Prosecutor to Review the Case
While the Sheriff’s Office has not made an arrest, the matter is not entirely closed. The Bonner County Prosecutor’s Office will conduct its own review of the circumstances surrounding Sparks’ death to determine whether any criminal charges should be filed. That evaluation is standard procedure in homicide cases, even when law enforcement declines to immediately arrest a suspect based on an apparent self-defense claim.
The investigation remains active as prosecutors weigh the available evidence against the legal standard established by Idaho’s self-defense statutes.
The incident is among several recent law enforcement matters drawing attention across Bonner County. Last month, a Moyie Springs man faces ten charges related to child exploitation images found at his residence, highlighting the ongoing workload facing local investigators and prosecutors.
No further public statements from Webster or his legal representation have been reported. Updates from the Bonner County Prosecutor’s Office are expected as the review progresses.
