Investigators used license-plate information and help from Columbus police to find Danielle Henry after Ibrahim Diakite was fatally injured.
WESTERVILLE, Ohio — By the time Westerville police began looking for Danielle Henry, investigators said they were pursuing a driver who had left two scenes in one morning: first a minor collision outside a Kroger and then a nearby roadway where another driver suffered fatal injuries beneath her vehicle.
The search lasted three days. Westerville Police Chief Holly Murchland said officers worked with the Columbus Division of Police and used automated license-plate-reading technology as they tried to locate Henry. She was arrested Oct. 25, 2025, in connection with the death of Ibrahim Diakite. The arrest ended the immediate manhunt but began a criminal case that would continue for nearly 10 months before Henry pleaded guilty and received a state-prison sentence in August 2026.
Police had several reasons to believe Henry might continue trying to avoid officers. Murchland said she had been accused of shoplifting at the Kroger before the traffic collision and was driving a stolen vehicle. Court records cited by local reporters showed active warrants involving allegations of theft, receiving stolen property and failure to comply. Other court-based reporting said Henry did not have a valid driver’s license. Murchland said after the arrest that the circumstances showed Henry had been strongly motivated to avoid being caught.
The event that triggered the homicide investigation occurred the morning of Oct. 22 at a Kroger at 55 W. Schrock Road. Henry and Diakite were involved in what investigators called a minor crash in the parking lot. A criminal complaint cited by the Columbus Dispatch said Henry left rather than remaining there. Diakite, who was reported to be working as a DoorDash delivery driver, followed her west on Schrock Road for almost a mile. Police said the vehicles reached the intersection of Schrock and Cooper roads, where the encounter became a direct confrontation.
Diakite drove in front of Henry and got out of his vehicle, according to the complaint. He stood in front of hers and then climbed onto the hood in an effort to prevent her departure. Investigators said Henry jerked or moved the vehicle several times while he remained there before accelerating to about 45 mph. Diakite then came off the hood and was pulled under the vehicle, police said. Authorities estimated he was dragged between 300 and 600 feet. He was taken to a hospital and pronounced dead.
Henry left that scene as well, according to police. By the time investigators were preparing charges, the case involved more than determining who had been driving. Officers needed to find a suspect who was no longer present, identify or track the vehicle and coordinate across jurisdictional lines in the Columbus area. Murchland later credited license-plate readers as one element of the effort that produced Henry’s location. The technology did not decide the criminal case; it served as an investigative tool used to locate the person police had already identified as wanted in connection with Diakite’s death.
After her arrest, Henry faced a series of allegations that included aggravated vehicular homicide and involuntary manslaughter, along with charges related to leaving the scene. A court set her bond at $750,000. Those early charges reflected prosecutors’ theory of the case but did not amount to a conviction. The distinction remained important until Aug. 11, 2026, when Henry entered a guilty plea. That plea resolved the question of whether the homicide prosecution would go to trial, although later news reports disagree about which homicide offense became the final conviction.
The Columbus Dispatch reported that Henry pleaded guilty to involuntary manslaughter and that Franklin County Common Pleas Judge Jeff Brown sentenced her Aug. 27 to an indefinite term of three to 4 1/2 years. Law&Crime and Fox News published a different account, saying the plea was to aggravated vehicular homicide and describing a term that could reach 5 1/2 years, with at least four years to be served. The reports consistently state that Henry’s driver’s license was suspended for life. The court’s final judgment entry was not available among the sources reviewed, leaving the sentencing discrepancy unresolved.
That disagreement does not alter the major investigative milestones. Police said Henry drove away after the initial collision, continued driving after Diakite tried to stop her and then left after he was fatally injured. Officers publicly sought her, used interagency cooperation and license-plate technology to assist the search, and arrested her three days later. Prosecutors then moved the case through the courts until Henry admitted criminal responsibility and was sentenced. Those points are consistently supported across the principal reports even where the exact final charge is described differently.
The police investigation also exposed a broader factual background that was not immediately apparent from the original description of a road confrontation. According to Murchland, the vehicle Henry was driving had been stolen and the parking-lot encounter followed an alleged shoplifting episode. The outstanding warrants reported in court records gave investigators additional reasons to believe avoiding police was a factor in Henry’s actions. Those allegations did not themselves prove the homicide charge, but they supplied context for the repeated departures that shaped both the police response and the later prosecution.
Diakite’s family provided a different kind of evidence about the consequences of the event. Relatives told WSYX that he had moved to Columbus from West Africa and was working to establish a life in the United States. His brother Mohamed said Ibrahim had also been his best friend. Family-based reports identified him as 31, while other coverage drawing on WBNS identified him as 38. Because reliable published sources remain inconsistent and no official record reviewed here resolves his age, the discrepancy remains noted rather than silently corrected.
The case also shows how the investigative phase and the adjudication phase answer different questions. The October police work was aimed at identifying what happened, locating Henry and supporting charges. The court process that followed determined whether the allegations would be contested at trial or resolved through a plea. Henry’s guilty plea meant witnesses did not have to present the entire case to a jury, and the sentencing hearing became the final major public stage. The life-long loss of her driving privileges was reported consistently even as outlets differed on the incarceration term.
As of Oct. 19, 2026, Henry is serving a prison sentence stemming from Diakite’s death, and no subsequent appeal or new prosecution related to the fatal incident was identified in the reliable material reviewed. Obtaining the Franklin County sentencing entry would be the clearest next documentary step for resolving the remaining disagreement over her exact offense of conviction and the limits of her prison term.
