Idaho Man Sentenced to Life in Prison for Father's Day Massacre of Neighbor's Family

In a case that has shocked the community, Majorjon Kaylor, a 32-year-old man from Idaho, has been sentenced to life imprisonment without the possibility of parole for the murder of a neighboring family, which included two teenagers. The tragic incident, motivated by revenge, has left the victims' families grappling with profound grief and loss. Court records reveal that First Judicial District Court Judge Barbara Duggan handed down the life sentence to Kaylor for the 2023 quadruple murder of Kenneth Guardipee, 65, his daughter Kenna Guardipee, 41, and her two children, Devin Smith, 18, and Aiken Smith, 16. During the sentencing hearing, Judge Duggan described the killings as a "particularly heinous event." The courtroom was filled with emotional testimonies from the victims' relatives, who shared their heartbreak and the devastating impact of the murders. David Silva, the grandfather of Aiken and Devin Smith, expressed his sorrow, saying, "He killed an entire branch of our family tree. Never any great-grandchildren to watch grow up. I lost my best friend (Aiken Smith). He spent hundreds of hours volunteering throughout the community. An entire beautiful family taken by one person." Gerri Silva, the mother of Kenna Guardipee, spoke about the unimaginable loss of three generations in one devastating blow, highlighting the profound emptiness left behind. Kenneth Guardipee's brother, Joe Guardipee, condemned Kaylor's actions, stating, "What a man you are. Not only did you destroy my family, but yours as well. You said you were protecting your children. Let me ask you: Who’s protecting them now?” The tragic events unfolded on Father’s Day, June 18, 2023, when deputies from the Shoshone County Sheriff’s Office responded to a distressing 911 call reporting multiple gunshot victims at a residence in Kellogg, Idaho. Upon arrival, they apprehended Kaylor, who was later charged with the murders of the four family members. Investigators determined that the shooting occurred following a disagreement between neighbors. The victims lived in the lower apartment of a duplex, while Kaylor and his family resided in the upper apartment. The families had been sharing the space for only a few weeks before the tragic incident. A probable cause affidavit revealed that the massacre transpired less than a week after Kaylor and his family lodged a complaint accusing Devin Smith of indecent exposure. In the police report, Kaylor's wife recounted an incident where Devin Smith allegedly stood fully naked in his ground-level bedroom window and engaged in inappropriate behavior while she and her young daughter were playing outside. After his arrest, Kaylor confessed to the murders. He explained that he attempted to discuss the alleged indecent exposure incident with Kenna Guardipee and her father but grew increasingly frustrated when they did not take the matter seriously. Kaylor admitted that he reached a breaking point and acted violently to address his anger, stating that he "snapped" and "lost control." The indictment outlined that all four killings were motivated by Kaylor's desire for revenge. Judge Duggan noted that Kellogg Police Officers had documented a report regarding the incident on June 13. Expressing frustration with law enforcement's response, Kaylor indicated that he wouldn't involve them if such an incident occurred again. On the day of the tragic events, June 18, Kaylor proceeded to shoot Kenna in the hand, torso, and temple, followed by shooting Kenneth in the torso and head. Subsequently, Kaylor entered the residence and shot Aiken in the back and temple, and Devin was struck by gunfire four times. Kaylor called 911 and said he "executed a f*****g pedophile and his family." When dispatch responded, "You shot four people and they’re all dead?" Kaylor confirmed, "Yes, I shot four people." During his sentencing, Kaylor opted not to address the court. His defense team urged the court to consider Kaylor's troubled background, highlighting a childhood marked by abuse, poverty, and instability. They also questioned why the court had not provided any recourse for Kaylor's family, such as issuing restraining orders, following the initial instances of misconduct. This tragic case underscores the devastating impact of unresolved neighborly conflicts and the far-reaching consequences of acts of revenge. The community continues to mourn the loss of the Guardipee family, while Kaylor's life sentence serves as a somber reminder of the need for early intervention and resolution of disputes. #MajorjonKaylor #KennethGuardipee #KennaGuardipee #DevinSmith #AikenSmith #IdahoMurders #LifeSentence Want to listen to ALL of our podcasts AD-FREE?
