Three people, including a 10-year-old boy, were killed Tuesday in a violent head-on crash on Highway 100 near Dundee Road in Franklin County. Investigators say a 2011 Nissan Sentra crossed the center line and slammed into a westbound 2020 Ford Explorer. Two people in the Sentra were pronounced dead at the scene, and the child later died at St. Louis Children's Hospital. The Explorer's driver, a 70-year-old woman from New Haven, survived with what authorities described as moderate injuries.

Crash details and victims

As reported by KSDK, the Missouri State Highway Patrol said the Sentra veered across the center line near Dundee Road and hit the Explorer head-on. Troopers identified the Sentra's occupants as a 42-year-old woman and a 47-year-old man, both from Hermann, and noted that neither was wearing a seat belt. The 10-year-old passenger, also from Hermann, was rushed to St. Louis Children's Hospital, where he later died from his injuries.

What authorities say

According to the Missouri State Highway Patrol, the force of the impact pushed the Explorer off the right side of Highway 100 and into a ditch. Troopers shut down the roadway while they documented the scene and cleared the wreckage. The Explorer's driver, a 70-year-old New Haven woman, was taken to a hospital with moderate injuries, authorities said. The patrol is leading the ongoing investigation and is keeping the official crash report updated as new information comes in.

Seat belts and safety

Troopers pointed out that the occupants of the Sentra were not buckled, a detail that frequently surfaces in fatal crash reports. Federal safety data show that seat belts cut the risk of death and serious injury by roughly half for adults and older children, and that booster seats and age-appropriate restraints significantly reduce injury risk for younger kids, according to the NHTSA and the CDC. Local officials routinely stress that proper restraints remain the best defense in high-impact crashes, particularly on two-lane highways where oncoming traffic is separated only by a painted line.

Investigation and next steps

The Missouri State Highway Patrol says its investigation is still in progress, and that toxicology work and detailed crash reconstruction can take several days. Authorities have not yet released the names of those killed, citing the need to notify relatives first. For the official record and ongoing updates, the patrol is posting information through its public Missouri State Highway Patrol crash-report system, and initial coverage has been provided by KSDK.
