Two teenagers in a car were killed when the driver pulled into a western Wisconsin intersection and struck a semitrailer truck, authorities said.

The crash occurred about 1:50 p.m. Monday in Clear Lake on Hwy. 63 at 60th Avenue, according to the Polk County Sheriff’s Office.

Emergency responders declared the car’s occupants dead at the scene. They were identified as driver Michael Magnuson and passenger Grace Schradle. Both 16-year-olds lived near the crash scene in the Clayton area. The truck driver was not hurt.

“Our thoughts and prayers go out to the family and community as we all continue to get through this tragic event,” a statement from the Sheriff’s Office read.

According to the Sheriff’s Office:

Magnuson heading east on 60th, slowed but did not obey a stop sign and hit the trailer portion of the semi as it traveled north on Hwy. 63.

The car rolled and came to rest in a ditch on its roof. The truck driver soon pulled over just north of the crash scene.
