ROLLERSVILLE - Three Louisville, Kentucky, residents were killed and another person was injured Friday morning when their car tried to pass traffic on U.S. 6 near Rollersville and was struck head-on by a semi-trailer, according to the Ohio Highway Patrol.

Four people were in the 2013 Dodge Avenger when it was hit by a 2016 Freightliner semi-trailer, west of Helena, at 7:45 a.m.

The car's driver, 21-year-old Matthew Bramel, 19-year-old front seat passenger Shelby Johnson, and a 25-year-old back-seat passenger Cody Nelson were pronounced dead at the scene, the highway patrol said in a news release. Another back-seat passenger, a 21-year-old Alexis Martin from New Albany, Indiana, was taken to St. Vincent Mercy Medical Center in Toledo by Sandusky County EMS.

The victim's names have not been released pending notification of family.

The semi driver, Christopher Marietta, 39, of Elizabethtown, Kentucky, attempted to take evasive action to avoid the crash, the patrol said. He was not injured.

U.S. 6 will be closed between U.S. 23 and Helena until the investigation is complete and EMA coordinates the cleanup of the diesel fuel spilled at the crash.
