Idaho man pleads guilty to fatally shooting family of 4 after he 'snapped'

SHOSHONE COUNTY, Idaho (TCD) — A man changed his plea to guilty this week after he was charged with killing four people during an argument because he was “concerned for his children.”

Court records show Majorjon Kaylor pleaded guilty on Dec. 18 to four counts of second-degree murder for the shooting deaths of 65-year-old Kenneth Guardipee, 41-year-old Kenna Guardipee, 18-year-old Devin Smith, and 16-year-old Aiken Smith. He was initially charged with four counts of first-degree murder and one count of burglary.

The Spokane Spokesman-Review reports prosecutors and Kaylor’s attorneys reached the plea agreement during a mediation outside of the courtroom.

On June 18 at 7:20 p.m., Kellogg Police Department officers were called to a home on the 500 block of West Brown Avenue, where they found four victims who had been shot and killed. Kenneth Guardipee was Kenna Guardipee’s mother. Aiken and Devin Smith were her children.

According to Kaylor’s arrest affidavit, the victims lived on the ground floor of an apartment building and Kaylor and his family lived above them.

A few days prior to the shooting, Kaylor’s wife, Kaylie, posted on Facebook alleging Devin Smith “exposed himself, was shaking his penis, and masturbating through a window in front of her and her juvenile daughters.”

After he was arrested, Kaylor told investigators Devin Smith “had been acting suspicious, watching his kids, and conducted acts of nudity in front of his children.” He also called Devin Smith a “pedophile.” Kaylor reportedly tried speaking with Kenna and Kenneth Guardipee about the teen’s actions, but they “didn’t seem to take his concerns with Devin Smith seriously.”

Kaylor told investigators he “‘snapped,’ ‘lost it,’ and ‘did something about it.’” All four victims suffered gunshot wounds to the head. Kenna and Kenneth Guardipee and Aiken Smith were shot once, but Devin Smith “had been shot multiple times from close range.”

Kaylor will be sentenced in March and faces 10 years to life in prison.
