Prosecutors say a 5-year-old Hyde Park student was run over after being dropped at the wrong stop.
BOSTON, MA — A former Boston school bus driver pleaded not guilty Thursday to manslaughter and other charges in the death of a 5-year-old boy, as prosecutors said the child was dropped at the wrong stop in Hyde Park and then run over while trying to cross the street.
The case has drawn broad attention in Boston because it centers on the death of a kindergartner, Lens Arthur Joseph, and on questions about school bus safety, driver oversight and contractor records. Prosecutors say Jean Charles failed to follow required safety steps on April 28, 2025. The defense called the death a tragic accident. The criminal case is moving ahead at the same time city officials continue to carry out safety changes ordered after an independent review of the school transportation system.
Charles, 39, of Brockton, was arraigned in Suffolk Superior Court on charges of involuntary manslaughter, reckless motor vehicular homicide and negligent motor vehicle homicide. He was released on $15,000 bail after pleading not guilty. A judge ordered him not to drive and to surrender his passport. Outside court, Suffolk District Attorney Kevin Hayden said the boy left the bus expecting to get home safely, but did not because of what prosecutors described as reckless conduct. Charles’ lawyer, Kenneth Anderson, said the defense sees the case as “a tragic accident” and said the family’s loss is impossible to measure. The next court date was set for May 11, giving both sides time to begin working through evidence that has been building for months.
Prosecutors said Lens, a student at UP Academy in Dorchester, was riding home with his older cousin when the bus missed the proper stop that would have let the children off on the same side of the street as their home. According to the prosecution’s account, Charles then failed to carry out the safety procedures required before a child crosses in front of a school bus. Hayden said Charles waited only a few seconds, did not make sure Lens’ position was clear, and drove forward, running over the boy. Prosecutors also said Charles failed to conduct a pre-trip inspection that would have shown the crossing bar was broken and a left rear tire was flat. They further alleged he did not stop at a stop sign. Some of those details are expected to be tested later in court, and the full factual record has not yet been presented to a jury.
Witness accounts added to the picture prosecutors laid out in court. One witness, according to the prosecution, said Charles appeared belligerent and annoyed with children on the bus before the crash. Prosecutors also said he struck a mail truck that day. Earlier public statements from Transdev, the contractor that runs Boston’s school buses, said Charles hit a car on the day of the fatal crash and failed to report it, something the company said would have led to his replacement if it had been disclosed right away. The exact sequence of every movement by the bus in the final moments before Lens was hit is likely to be a central issue as the case moves forward. Investigators have said surveillance footage from the bus camera and eyewitness testimony were part of the evidence presented to the grand jury. The defense has not yet laid out its full response to the prosecution’s version of events.
The death set off parallel investigations and public scrutiny well beyond the criminal case. Boston Mayor Michelle Wu and Superintendent Mary Skipper announced an outside review weeks after the crash, saying the city needed a full accounting of safety policies and performance under its contract with Transdev. That review was separate from the criminal investigation led by the district attorney’s office. Boston Public Schools relies on school transportation for more than 20,000 students each day, and Transdev has been under contract since 2013 to hire, train and manage roughly 750 drivers while maintaining and operating the fleet. City officials said the independent review found system problems that demanded quick changes, including stronger oversight, daily reviews of crashes and safety incidents, and closer participation by district leaders in accident review meetings.
Officials also disclosed that Charles had an expired state-required school bus certificate on the day of the crash. City officials said Transdev had employed him since May 2023 and that his record included four minor incidents before April 28, including two earlier in April 2025. After those incidents, officials said, he was pulled off the road for two days for retraining. Wu later said the driver involved on April 28 should not have been on the road. The independent review also examined broader record-keeping and oversight issues, and officials said the city and school district would adopt all of its recommendations. The review did not decide criminal responsibility for Lens’ death, but it sharpened questions about whether contractor controls, certification checks and day-to-day supervision were strong enough before the crash.
The criminal case is not the only legal action tied to the boy’s death. Lens’ family filed a civil lawsuit in Suffolk County Superior Court in July 2025 against Transdev entities and Charles, alleging negligence in hiring, training and supervision. The suit also argued that safety technology was missing or not in place, listing items such as stop-arm cameras, extended stop arms, crossing arms, surround cameras, pedestrian detection sensors and automatic braking. Civil claims and criminal charges operate on separate tracks, and the lawsuit does not determine guilt in the criminal case. But together, the proceedings have kept the focus on both the conduct of the driver and the safeguards built into the school bus system. As of Thursday, the family’s civil case remained pending while the criminal prosecution took a major public step with Charles’ arraignment.
Prosecutors added another detail Thursday that broadened the picture they presented of Charles’ conduct after Lens’ death. In court, they said Charles had been involved in a hit-and-run in Brockton in August 2025, months after the fatal Hyde Park crash. That allegation did not form the basis of the charges in Lens’ death, but it surfaced during the arraignment as prosecutors argued for conditions of release. The defense did not publicly give a detailed reply to that claim at the hearing. In the courtroom and outside it, the sharper point remained the death of a child whose family expected a normal ride home from school. Hayden’s remarks reflected that grief, while Anderson’s comments underscored the defense position that the case is a terrible accident rather than a crime. Both messages showed how much emotional weight the case carries for the family, the school community and the city.
For now, Charles remains free on bail under court-ordered conditions, and the charges remain pending. The next key milestone is his May 11 court appearance, when the case is expected to return to Suffolk Superior Court as prosecutors and defense lawyers continue to prepare for the next stage.
