In the quiet community of Moyie Springs, Idaho, the life of 54-year-old Caucasian woman, Susan Maria Dabbs, came to a tragic end on September 22, 2020. What initially appeared to be a horrific accident, a house fire that claimed her life, would slowly unravel into a complex homicide investigation centered around her husband.
On that Tuesday evening, at approximately 8:30 p.m., a 911 call was placed by Shannon Dabbs, Susan's husband.
He reported that he had shot his wife and that their cabin on Perkins Lake Road was on fire. When sheriff's deputies arrived at the scene, they found the cabin engulfed in flames and promptly arrested Shannon. He claimed that he had acted in self-defense during a heated argument with his wife about their impending divorce. According to his account, Susan had started a fire on their bed and then brandished a gun, forcing him to shoot her in the chest.
However, as investigators from the Idaho State Police, the Boundary County Sheriff's Office, the Idaho State Fire Marshal, and the Bureau of Alcohol, Tobacco and Firearms delved deeper into the case, inconsistencies in Shannon Dabbs' story began to emerge. A crucial piece of evidence came from the autopsy, which revealed that Susan Dabbs had no smoke in her lungs, directly contradicting the narrative that she was alive and present in the burning room. Furthermore, investigators found Shannon's description of how quickly the fire had spread to be implausible. When he was taken into custody, his clothes did not smell of smoke, another detail that cast doubt on his version of events.
After a nearly three-year-long investigation, Shannon P. Dabbs, then 57, was arrested in July 2023. He was formally charged with second-degree murder and first-degree arson in connection with the death of his wife. Court documents allege that he shot Susan multiple times in the head and chest before intentionally setting fire to their home. Prosecutors have suggested that the motive behind the alleged murder was the couple's pending divorce. The case went to trial, but in January 2025, a judge declared a mistrial after the jury was unable to reach a unanimous verdict. A retrial for Shannon Dabbs was subsequently scheduled to begin in October 2025.
