WARSAW — A South Whitley woman was killed early Monday morning after her SUV was rear-ended by a semi.

Kosciusko County Sheriff’s deputies and emergency personnel were called at 3:40 a.m. Monday to the intersection of U.S. 30 and S.R. 19. Crews found a woman pinned inside a 2015 Chevy Traverse.

The Kosciusko County coroner arrived and pronounced Vicki Sue Bartz, 52, of South Whitley dead at the scene.

The Kosciusko County Fatal Team found that Bartz was stopped at the red light in the westbound lanes of U.S. 30 when a tractor-trailer driven by Waldemar A. Palys, of East Stroudsburg, Pennsylvania, rear-ended her SUV “at highway speed.” Investigators believe Palys might have fallen asleep before the crash.

The crash remains under investigation by the Kosciusko County Sheriff’s Department.
