Search warrant: ammunition found in diaper bag after fatal Plymouth shooting

Police are working to find out what exactly happened to seven-year-old Keyaris Samuels who accidentally shot himself last week in Plymouth, Minnesota.

On May 16 around 3 p.m., Plymouth officers were dispatched to the 6000 block of Shenandoah Lane where they found a boy with a gunshot wound to the head. When emergency personnel arrived they performed CPR, but the boy was pronounced dead at the scene.

Family said Keyaris accidently shot himself in the head after finding a loaded gun in a box with a hoverboard. The search warrant, however, does not mention a hoverboard box.

According to the search warrant, police discovered a box of .357 ammunition in a diaper bag in home. The box was half-full and found to be of the same caliber as the handgun that was lying next to the victim.

The ammunition and the handgun were taken to a forensic lab for DNA and print processing. Officers discovered that multiple people handled the gun that day, including his 11-year-old brother.

During the investigation, officers learned that the child's mother denied she ever kept a gun in her house and was unaware of how Keyaris obtained it. Officers learned she had a friend who visited the house earlier in the day and she believes that friend "must have placed the gun somewhere in her house."

In the search warrant, officers state they believe the gun was "negligently stored," endangering the child's life.

Officers also learned that friend did not show up for a required meeting with his parole officer hours before the incident. He is in custody, and officers will test his DNA to see if it matches DNA on the gun.
