Three children and three adults were hospitalized Wednesday after a two-vehicle crash near Hebron when a car ignored a stop sign, police said.

The Hebron-Alden-Greenwood Fire Protection District was called at 2:59 p.m. Wednesday to Thayer Road and Route 47 in Greenwood Township, which is south of Hebron, for a vehicle crash.

Fire Chief Thomas Linneman said that fire crews found heavy damage to a red GMC Acadia and a black pickup truck that were involved in the crash, which involved a total of seven people.

One of the victims was trapped in the GMC and required firefighters to extricate them, Linneman said.

Five victims from the GMC were transported to Northwestern Medicine McHenry Hospital and one of them was transported to Northwestern Medicine Huntley Hospital. The 46-year-old South Barrington man driving the pickup truck was uninjured.

Linneman said that the victims had injuries ranging from minor to critical. Police said that a 16-year-old, 4-year-old and a 2-year-old were among the victims injured.

McHenry County Sheriff’s Spokeswoman Sandra Rogers said that the pickup truck, which was carrying a trailer, was driving southbound on Route 47. The GMC was driving eastbound on Thayer Road when it ignored the stop sign and struck the truck.

The driver of the GMC, Blanca Mercado, 27, of Harvard, was cited for operating an uninsured vehicle and disobeying a stop sign.

Two medical helicopters were requested to the scene but were unable to fly due to weather conditions.

Firefighters from Richmond, Harvard, Woodstock, Wonder Lake and McHenry along with a Mercy Health Field Physician assisted Hebron at the scene.
