On the evening of Friday, February 6, 2026, five-year-old Jaylon Young of the Florissant area died after suffering a gunshot wound inside a home in the 12400 block of Jerries Lane in Black Jack, north St. Louis County. Police responded about 9:40 p.m. to a report of an accidental injury; Jaylon was taken to a local hospital and later died from his wounds.

Investigators determined the child found a loaded firearm that had been left unsecured and within reach while he was unattended. Jaylon’s uncle, 29-year-old Rayvon McPherson of Black Jack, was arrested after acknowledging in a 911 call that the gun belonged to him and admitting fault. The St. Louis County Prosecuting Attorney’s Office charged McPherson with first-degree child endangerment resulting in the death of a child, and a judge set a $250,000 cash-only bond.

If anyone has information about the circumstances at the home that night or knew Jaylon, please share what you know.
