A Detroit mother has been charged after prosecutors said her 11-year-old son found an unsecured handgun in a parked vehicle and fatally shot his 6-year-old sister in the head while their mother was inside a restaurant in a shopping plaza.
The case quickly became one of the most closely watched child safety prosecutions in Wayne County because it combines a child’s death, an unsecured firearm and Michigan’s still-new safe-storage law. Prosecutors charged Tonya Charisse-Annice Johnson, 41, with a firearms safe-storage violation, three counts of second-degree child abuse and four counts of felony firearm. The girl’s death left four surviving children at the center of a case that prosecutors said will carry lasting trauma far beyond the courtroom.
According to police and prosecutors, the shooting happened about 12:06 p.m. on Monday, March 2, in a shopping center parking lot on the 9700 block of Harper Avenue near Gratiot on Detroit’s east side. Authorities said Johnson had driven to the plaza with her five children, ages 2 to 11, and went inside a restaurant while the children stayed in the vehicle. During that time, prosecutors said, one of the children found a handgun under the front driver’s seat. Prosecuting attorney Aniela Boscia said the boy then turned and shot his 6-year-old sister in the back of the head. Medics took the girl to a hospital, where she died. Police have not publicly identified the child in charging documents, and officials have not said how long the mother had been away from the vehicle before the shot was fired.
As investigators pieced together what happened, they said the gun was both loaded and unsecured in a place where a child could reach it. Police later found other unsecured weapons at Johnson’s home, according to prosecutors and local reports. Authorities have not publicly detailed how many guns were found there or whether any of those weapons led to separate counts. Detroit police also have not publicly explained why the handgun was being kept in the vehicle, how long it had been there or whether the children had previously known where it was stored. FOX 2 reported that the boy told investigators the gun had always been left in the vehicle but that he did not know it was loaded. Those unanswered questions have become central to the case because prosecutors are arguing that the risk to the children was not sudden or unforeseeable, but the result of a weapon left within easy reach.
The legal case now turns on both the facts of the shooting and the obligations created by Michigan’s secure-storage law. Prosecutor Kym Worthy said the allegations were among the worst child safe-storage cases her office had seen. Under Michigan law, gun owners must secure unattended firearms when minors are present or likely to be present. If a child gets access to the weapon and causes death or serious injury, the violation can be charged as a felony. Prosecutors also filed three counts of second-degree child abuse and four counts of felony firearm, signaling that the case is not being treated as a single storage lapse but as a broader failure to protect the children who were in the vehicle. Authorities have not publicly said whether more charges could follow, but the current filing already places the case among the more serious early prosecutions brought under the state’s updated law.
Johnson made her first court appearance on Thursday and pleaded not guilty. She appeared by Zoom, and the judge set bond at $30,000 cash surety. She also was ordered to have no contact with her children while the criminal case moves forward. During the hearing, Boscia called the shooting an avoidable tragedy and said the surviving children would live with the memory of what they saw. FOX 2 reported that prosecutors told the court Johnson had a concealed pistol license and understood the rules tied to storing a firearm. Defense attorney Phil Ragan told the court that no one felt worse than Johnson. The next hearing was scheduled for March 13, when the court is expected to take up the case again as prosecutors continue presenting the basis for the charges.
Outside court, the case has also unfolded as a family loss before it became a legal test of the safe-storage law. The child’s grandmother, Tonya Wheeler Johnson King, told ClickOnDetroit that her granddaughter was a joyful girl who loved church, playing and spending time with siblings and cousins. She described the child as a helper in the family and said she was still searching for answers about how the shooting happened. Her comments added another layer to a case already defined by the stark facts in court records: five children in a vehicle, a handgun under a seat and one shot that changed the family’s life in seconds. That contrast has shaped much of the public reaction, with relatives speaking in the language of grief while prosecutors describe a preventable death supported by physical evidence and the state’s firearm storage rules.
As of Sunday, the charges remained pending, Johnson had entered a not guilty plea and authorities had not announced any additional counts or a final determination beyond the existing allegations. The next public milestone in the case is the March 13 court hearing in Detroit.
