Three people died in a traffic crash early this morning in Marion County and the Tennessee Highway Patrol is asking the public's help to find out whether another vehicle was involved.

Nicholas S. Clayton, 20, and Emily F. Clayton, 21, both of Sale Creek, died along with 24-year old Annie E. Blevins of Chattanooga, according to a THP news release.

They were traveling south on Big Fork Road about 4:20 a.m. Saturday in a 2001 Jeep driven by Eric D. Blevins, 37, the THP release said.

The driver lost control in a right-hand curve and overcorrected and the Jeep rolled over. Investigators believe another vehicle may have been involved, according to the release.

The Claytons and Annie Blevins were not wearing seatbelts and were ejected, the release said. Eric Blevins was airlifted to Erlanger hospital where his condition was not immediately available this evening.

The Highway Patrol's Critical Incident Response Team and Criminal Investigations Division are investigating the deadly crash.

Anyone with information is urged to call the THP's Chattanooga office at 423-634-5856.
