The Monroe County Sheriff's Office and Ohio State Highway Patrol in Van Wert are both investigating fatal accidents involving teen drivers.
In Ash Township, Michigan, 17-year-old Chelsea Klocek was killed in a two-vehicle crash at the intersection of N. Telegraph Road and Sigler Road.
The Newport teen was a passenger in 17-year-old Manushaqe "Violet" Pasho's Jeep when the pair collided with a semi-tractor trailer around 2:30 p.m. on Wednesday.
Pasho was critically injured in the accident and was taken to Oakwood-South Shore Hospital in Trenton for treatment.
The semi-truck driver was not injured in the crash.
Less than 30 minutes later across the border in Ohio, 17-year-old Robert Seffernick was killed in a 2-vehicle crash.
Just before 3 p.m., the Melrose teen collided with a Jeep along SR 637 near Elm Sugar Road in Hoaglin Township.
Troopers say that Seffernick lost control of his vehicle on the snowy roadway and went left of center.
The Jeep's driver, 64-year-old David Simko of Toledo was seriously injured and was taken by Samaritan LifeFlight to Parkview North Regional Medical Center.
In both crashes, investigators do not believe that alcohol played a role.
Everyone involved in both crashes were also wearing their seatbelts.
