WOODSTOCK, Ill. (AP) — Authorities in northern Illinois say three men were killed when a vehicle they were in slid off a road and slammed into a tree.

The Northwest Herald reports that the crash happened at about 3:30 on Sunday morning in unincorporated Woodstock.

The McHenry County Sheriff’s Department says the 20-year-old driver of a Jeep Cherokee and two passengers, also in their early 20s, were pronounced dead at the scene. Deputy Sandra Rogers says a 20-year-old Woodstock man who was also in the vehicle suffered life-threatening injuries.

The investigation is continuing but Rogers says the Jeep was traveling above the 45 mph speed limit at a time when it was foggy and the roads were slippery.

None of the names of the victims have been released. All lived in Woodstock.
