Nathaniel Archuleta, an 18-year-old from Peoria, has been charged with involuntary manslaughter and other firearm-related offenses following the fatal shooting of 20-year-old Mary Halcomb. The incident occurred on Friday night at a residence on South Griswold Street, where police found Halcomb with a gunshot wound and she was pronounced dead at the scene. Archuleta, who was present at the time, faces charges for unlawfully possessing a firearm and recklessly handling a loaded gun. His detention hearing has been postponed until Wednesday, and he remains in the Peoria County Jail. An autopsy for Halcomb is scheduled, and the investigation is ongoing. This tragic event raises concerns about gun safety and youth access to firearms in the area.
