What was hidden beneath the mattress…
Witnesses say a 10-year-old boy quietly reached under a bedroom mattress and retrieved a concealed object, and moments later a baby suffered a severe head injury in a heartbreaking case that has stunned Missouri.
The relationship between the child and the infant has not yet been clarified, and investigators are still working to piece together exactly what led to the incident.
Now, the boy has become the youngest person in Missouri state history to face a serious case in juvenile court—while one unanswered question continues to haunt the investigation: how did such a dangerous object end up within a child’s reach?
***************
A devastating case of gun violence has shocked the state of Missouri after a 10-year-old boy was formally charged with first-degree murder for allegedly shooting a 7-month-old baby girl in the head. Due to his young age, the identity of the preteen suspect has been legally withheld by authorities. Legal experts and local reports indicate that the boy is believed to be the youngest individual to ever face a murder charge in the history of the state.

The catastrophic incident unfolded on Friday when officers with the St. Louis Metropolitan Police Department rushed to a local residence following urgent reports of shots fired. Upon entering the home, first responders discovered the infant victim, identified as Kiyomi Parker, suffering from a critical gunshot wound to her head. Officers immediately initiated life-saving measures on-scene before rushing the baby to a nearby hospital. Tragically, despite the aggressive medical interventions, the infant succumbed to her severe injuries shortly after arrival.
HIDDEN UNDER A MATTRESS: HOW THE PRETEEN SECURED THE WEAPON
According to court documents obtained by local news outlet First Alert 4, the sequence of events inside the home was reconstructed through harrowing eyewitness testimonies. Witnesses recounted that the 10-year-old boy located a loaded firearm hidden beneath a mattress in one of the residential bedrooms. He retrieved the weapon and fired a single shot, striking the 7-month-old infant. A 7-year-old child was also present in the home when the gunfire erupted, narrowly escaping physical harm.
During subsequent police interrogations, the accused preteen shooter admitted to detectives that he was fully aware of where the firearm was stashed. He stated that the weapon was easily accessible to him and confessed that he had previously retrieved and handled the handgun on prior occasions before the fatal shooting occurred.

The investigation quickly pivoted toward the owner of the firearm, identified as the victim’s 19-year-old father, Ca’Marion Pawnell. Court documents confirm that Pawnell admitted to law enforcement that he had intentionally stashed the loaded gun under the mattress where the young boy ultimately found it. At this stage of the ongoing investigation, the exact familial or social relationship between Pawnell and the 10-year-old suspected shooter remains unclear.
SEVERE CRIMINAL CHARGES AND ADULT RESPONSIBILITY
The legal fallout from the tragedy has resulted in severe criminal prosecutions in both the juvenile and adult court systems. The 10-year-old boy has been formally remanded into custody and charged with first-degree murder within the Missouri juvenile court system.
Simultaneously, Ca’Marion Pawnell was arrested and hit with heavy criminal charges for his role in facilitating the fatal environment. Under Missouri statutes regarding adult responsibility in child-related firearm deaths, Pawnell has been charged with:
One count of second-degree murder

One count of first-degree endangering the welfare of a child resulting in death
Two counts of endangering the welfare of a child creating substantial risk
Following his initial booking and processing by St. Louis police, a judge ordered that Pawnell be held behind bars at the regional detention center without bond. As the community struggles to process the loss of baby Kiyomi, local advocacy groups and law enforcement officials are using the high-profile tragedy to reiterate the absolute necessity of secure firearm storage, emphasizing that unsecured weapons in households with minors carry permanent, fatal consequences.
