City officials said in a statement that the crash involved two vehicles.

A preliminary investigation showed that a 2026 Hyundai Sonata was traveling northbound on Skokie Valley Road when it struck a 2006 Toyota Sienna, which was turning southbound onto Skokie Valley Road from westbound Park Avenue.

The driver of the Toyota, identified as Joan Scaccia, 73, of Wilmette, had to be extricated from her vehicle, according to Lake County Coroner Jennifer Banek.

Scaccia suffered life-threatening injuries and was transported to Endeavor Highland Park Hospital where she was pronounced dead in the emergency room.

Fire department radio traffic indicated they were a “yellow” patient, indicating they suffered moderate injuries that were not believed to be life-threatening. They were transported to Endeavor Health Evanston Hospital.

Autopsies were performed on Monday on Scaccia and Paz and preliminary results confirmed both died as a result of blunt force injuries from the crash, Banek said.

The Lake County Major Crash Assistance Team (MCAT) was activated and responded to conduct a full crash investigation.

Route 41 at Park Avenue was shut down due to the investigation and a detour at Central Avenue was in place. The road was reopened around 7:30 p.m.
