  • 2 killed in wrong-way crash on I-4 early Sunday
  • George Stephan, Gretchen Roberts killed near Lake Monroe
  • Troopers say they weren't wearing seat belts

George Stephan, 20, of Lake Mary and Gretchen Roberts, 19, of Maitland, were killed about 4 a.m. west of the St. Johns River Bridge in Seminole County, a Florida Highway Patrol report says. 

Troopers said a 2014 Honda Civic driven by Stephan was traveling westbound in the eastbound lanes of I-4.

James Marchesani, 66, of Pennsylvania, heading east, tried to swerve out of the way, but the front of his 2012 Mercedes SUV struck the Civic.

FHP said Stephan and Roberts were not wearing seat belts, troopers said. Marchesani was wearing a seat belt and incurred minor injuries. He was taken to Central Florida Regional in Sanford.

The crash remains under investigation.
