A 10-year-old boy is charged with first-degree murder in the shooting death of his 7-month-old niece at a home in St. Louis, Missouri, court officials and police said. The reports describe how authorities responded to the residence and found the infant, identified as Kiyomi Pawnell-Parker (also reported as Kiyomi Parker), suffering from a gunshot wound and later dying. According to police, the boy accessed a firearm kept under a mattress. Because of his age, he is not named in the coverage.

The New York Times reports that the baby’s father, who owned the weapon, has also been charged, while other outlets focus primarily on the juvenile suspect’s murder charge. The exact charges against the father and the full circumstances of how the firearm was secured are not detailed in the provided summaries. The case is ongoing and will proceed through the court system as charged.
