Idaho father killed 4 in dispute over neighbor teen’s behavior, police say

The families shared a duplex, and the teen allegedly exposed himself to the shooter's daughters.

BOISE, Idaho (AP) — An Idaho father killed a neighboring family during a dispute over allegations that the neighbor’s 18-year-old son exposed himself to the man’s children, a police document alleges.

Majorjon Kaylor, 31, of Kellogg, is charged with four counts of first-degree murder in the Father’s Day shooting.

A probable cause affidavit from Idaho State Police Detective Justin Klitch says Kaylor shot Kenneth Guardipee, 65; his daughter Kenna Guardipee, 41; and her youngest son, 16-year-old Aiken Smith, in the temple at close range. Smith’s older brother, 18-year-old Devin Smith, was shot multiple times in the head, according to the document.

Kaylor and his wife told investigators that several days earlier Devin Smith had masturbated in front of his bedroom window in full view of the Kaylors’ young daughters. The families shared a duplex, and the girls were playing outside in the yard when the exposure allegedly occurred.

The alleged exposure was reported to the police, and the police report was forwarded to the county prosecutor so a criminal charge of indecent exposure could be filed.

But on Sunday around 7:20 p.m., the Kaylors had an argument with Kenna and Kenneth Guardipee over how the allegations were being handled. That’s when Majorjon Kaylor allegedly shot both the adults in the head before going inside the family’s apartment to kill the two sons, according to the report that was released Tuesday evening.

The weapon was said to be a .45-caliber semiautomatic handgun. The number of shell casings at the scene indicated the shooter most likely had to change magazines during the attack, investigators said in the document.

A family friend of the Guardipees’ told the Spokane Spokesman-Review that Devin Smith had a learning disability and struggled socially.

Kaylor is being held without bond and has not yet entered a plea. A preliminary hearing has been set for July 3.
