A tragic crash on an Ohio highway claimed the lives of six people and injured 18 others on Tuesday morning. A charter bus carrying 54 students and chaperones from Tuscarawas Valley High School was rear-ended by a semitrailer on Interstate 70 West in Licking County, near the Smoke Road underpass. The bus was part of a convoy of three buses heading to a field trip in Columbus, according to the Ohio State Highway Patrol. The collision triggered a chain reaction that involved at least five vehicles, including two other commercial vehicles and two passenger cars, the National Transportation Safety Board said. Three students on the bus died at the scene. They were John W. Mosely, 18, Jeffery D. Worrell, 18, and Katelyn N. Owens, 15, all from Tuscarawas County. The bus driver and 15 other students were taken to a local hospital with various injuries. The occupants of one of the passenger cars also died at the scene. They were Dave Kennat, 56, Kristy Gaynor, 39, and Shannon Wigfield, 45, all from Navarre. The driver of the other passenger car and the driver of one of the commercial vehicles were hospitalized, while the driver of the third commercial vehicle was released on the scene. The cause of the crash is still under investigation. The NTSB said it will send a team of 10 investigators to the site.
