The 9mm handgun that killed 2-year-old Jacarion Gladden on July 31 was left loaded and unattended on a table beside a living room sofa shortly before the child was shot, according to two arrest warrants filed in the case. The warrants charge Jacarion’s mother, Toni Lashay Gladden, 26, and her boyfriend, Shazeem Tyrell Hayes, 18, with unlawful conduct toward a child.
