Prosecutors say Jean Charles failed to follow safety steps before a Hyde Park drop-off that ended with a 5-year-old child under the bus.
BOSTON, Mass. — A former Boston school bus driver pleaded not guilty Thursday to charges tied to the 2025 death of 5-year-old Lens Arthur Joseph, a Hyde Park kindergartner prosecutors say was run over moments after getting off the bus near his home.
Jean Charles, 39, of Brockton, was arraigned in Suffolk Superior Court on charges of involuntary manslaughter, reckless motor vehicular homicide and negligent motor vehicle homicide. The case has become one of the most closely watched child-safety cases in Boston because it reaches beyond one crash and into questions about driver oversight, vehicle inspection and school transportation rules in the city. Charles was released on $15,000 bail after pleading not guilty, and the criminal case now moves forward as Lens’ family continues a separate civil lawsuit against the bus contractor.
The charges stem from the afternoon of April 28, 2025, when Lens, a kindergarten student at UP Academy in Dorchester, was riding home on a Boston school bus operated by Transdev, the private contractor used by Boston Public Schools. Prosecutors told the court that Charles missed a series of designated stops that day, including the stop meant for Lens and his older cousin, and let the children off at a different location on Washington Street in Hyde Park. Assistant District Attorney Ursula Knight said the boy then moved in front of the bus to cross the street. “Without looking for Lens, checking his mirrors, without assuring that Lens had reached safety, the defendant accelerated,” Knight said in court. Prosecutors say the child was pulled under the bus and killed.
In court, prosecutors described a chain of failures they say began before the bus ever left for its route. Knight said Charles did not complete a proper pre-trip inspection, and that such an inspection would have revealed two defects serious enough to keep the bus out of service: a broken crossing bar and a rear left tire that was flat and on its rim. Those details sharpened the prosecution’s argument that the case was not a split-second mistake alone, but part of a broader pattern of neglect. Prosecutors also raised other conduct by Charles, saying he had previously struck a postal truck while students were on board and left the scene, and that another later hit-and-run case remains pending. Defense lawyer Kenneth Anderson called the death a “tragic accident” and said Charles has struggled since the crash. The defense did not contest the family’s loss, but argued the case should be understood as an accident rather than a crime.
The case has also drawn attention because of what emerged in the months after Lens’ death. News reports in 2025 found that Charles’ school bus credential had lapsed in December 2024, months before the crash. Transdev said at the time that the driver had been notified, while Boston Public Schools said it did not independently verify whether contracted drivers were properly licensed before they got behind the wheel. Charles, who had worked for Transdev since May 2023, resigned in May 2025 before a scheduled termination hearing. In August, a city-commissioned independent review examined school transportation safety after Lens’ death and concluded that Boston and its contractor needed broad reforms. Mayor Michelle Wu and Superintendent Mary Skipper said the city would adopt all recommendations from that review. The report was not a criminal finding, but it added official weight to complaints that the system had weak oversight and unreliable records.
The legal process is now moving on two tracks. Criminally, Charles has denied the charges and was ordered not to drive and to surrender his passport as conditions tied to his release. He is due back in court on May 11. Civilly, Lens’ family sued Transdev in July 2025, alleging negligence in hiring, training and supervision and arguing that the contractor failed to use or install safety technologies that could have better protected children near the bus. Their lawyers have said the family wants accountability not only for Lens’ death but also for the policies that allowed the driver to remain on the road. Prosecutors, meanwhile, have said the grand jury relied on surveillance video from the bus and eyewitness testimony in returning the indictments earlier this month.
The courtroom on Thursday reflected how raw the case remains nearly a year later. Family members of Lens and relatives of Charles sat through the hearing as lawyers and prosecutors laid out sharply different views of what happened. Lens’ father was seen wiping away tears after the proceeding. Outside court, grief mixed with a more procedural reality: a child is gone, the driver is now formally charged, and city officials are still being pressed to explain how a driver with an expired credential and an allegedly unsafe bus was carrying schoolchildren at all. The questions that first spread through Hyde Park after the crash have not faded. They have instead narrowed into a criminal case with names, dates, evidence and a next court date.
The case now stands at the arraignment stage, with Charles free on bail and scheduled to return to Suffolk Superior Court on May 11 as both the criminal prosecution and the family’s civil case continue.
