A woman was seriously injured in a crash involving three vehicles Tuesday in DeKalb County.

Alice R. Sanders, 57, was parked about 4:15 p.m. when another vehicle collided with the back end of her vehicle on Route 38 and Malta Road in Rochelle, the sheriff’s office said.

Sanders was stopped facing westbound in a Ford hatchback with Oliver Penney, who was in a separate vehicle. A third person, 34-year-old Jon Henley, drove up from behind in a Ford SUV and failed to reduce his speed, police said.

Henley struck the back end of Sanders’ vehicle, pushing her vehicle into Penney’s Ford Focus, police said.

Sanders was extricated from her vehicle and was taken to Northwestern Medicine Kishwaukee Hospital in DeKalb. She was later flown to Saint Anthony Hospital with serious injuries. She was wearing her seatbelt at the time of the crash, police said.

All three vehicles were towed from the scene, police said.

Penney and Henley refused medical attention. Henley was issued a citation for failing to reduce his speed to avoid an accident, police said.

The sheriff’s office previously stated the three vehicles involved belonged to police.
