A car was reported to be driving recklessly over 100 mph before smashing into an SUV towing an RV in Richmond Sunday evening, causing a fiery crash that injured both drivers, one critically, and damaged a building.

A Richmond police officer was conducting an unrelated traffic stop when he saw a silver sedan traveling at a high rate of speed westbound on Route 173 in the oncoming lane of traffic around 7:37 p.m. Sunday, Richmond Police Chief Ciro Cetrangolo said.

According to police radio traffic and witnesses, the Toyota was driving at around 100 mph. The speed limit for that stretch of Route 173 is 35 mph.

“Shortly thereafter, the officer came upon a two-vehicle crash at the intersection of Route 173 and Route 12,” Cetrangolo said.

The crash involved the sedan, a silver 2010 Toyota Corolla, that was seen driving recklessly moments earlier.

An initial investigation shows an adult male was driving the Toyota westbound on Route 173 approaching Route 12 at a high rate of speed.

The Toyota entered the intersection and crashed into a white 2021 Nissan Armada, driven by an adult female, that was towing a camper trailer.

The impact caused the camper trailer to separate from its frame and end up on Route 12 south of the intersection.

Both the Toyota and Nissan sustained major damage.

The Richmond police officer who pulled up on the crash immediately requested additional police units and fire/rescue personnel to respond, according to radio traffic.

The man in the Toyota was reportedly unconscious but breathing.

Police officers and McHenry County sheriff’s deputies, along with the Richmond Township Fire Protection District and multiple other area fire departments, rushed to the scene.

Both of the drivers were trapped and were extricated by firefighter/medics.

There were no other occupants in either vehicle.

LifeNet 3-1, a medical helicopter based out of McHenry, was requested to land at the Richmond Fire Station located at 5601 Hunter Drive and meet firefighter/medics.

The woman in the Nissan was transported by ambulance to Northwestern Medicine McHenry Hospital in stable condition.

The man in the Toyota was transported briefly by ambulance to the fire station, where he was then transferred to the flight crew and flown to Advocate Condell Medical Center in Libertyville, a Level 1 trauma center.

The man was in critical condition at the time of transport, fire officials said.

“Preliminary findings indicate that vehicle speed appears to be a contributing factor in the crash,” Cetrangolo said.

The crash left a large debris field on Route 173.

A business on the corner, Value Discount Flooring, was damaged, along with a nearby utility pole.

Due to the severity of the crash, the McHenry County Major Crash Assistance Team (MCAT) – composed of investigators from the Cary, Harvard, Johnsburg, McHenry, Spring Grove, Richmond and Woodstock police departments – was activated and responded to reconstruct the crash.

All four directions of Route 12 and Route 173 were shut down into the early morning hours while MCAT worked the scene.

Investigators were seen taking photos, measurements and conducting interviews with bystanders as part of the accident reconstruction.

An employee at the nearby Gigi’s Cafe, named Charles, told Lake and McHenry County Scanner he was inside working when he heard an explosion-like noise.

“I knew it wasn’t fireworks,” he said.

Charles immediately looked outside to see the crash, with flames coming from the engine compartment area of the Toyota.

He quickly grabbed the restaurant’s fire extinguisher and ran outside.

Numerous other good Samaritans worked together to check and render aid to those involved in the crash.

“He’s breathing, he’s breathing!” Charles heard them saying about the man in the Toyota.

Cetrangolo credited the good Samaritans for their actions.

“The Richmond Police Department wishes to thank the good Samaritans who stopped and assisted at the scene before police and fire personnel arrived,” the police chief said.
