Authorities have released the identity of a 63-year-old woman who died after a motorcycle slammed into a stopped car and rolled over, leaving her husband critically injured, near Wauconda.

An autopsy performed Wednesday showed that Laura Siano, 63, of Northbrook, died as a result of blunt force injuries from a vehicle crash, according to Lake County Coroner Jennifer Banek.

The Wauconda Fire District and Lake County Sheriff’s Office responded around 1 p.m. Tuesday to the intersection of Route 12 and Lake Shore Drive in unincorporated Wauconda for a vehicle crash with injuries.

Sheriff’s deputies arrived and located two people, including Siano, with critical injuries, according to Lake County Sheriff’s Office Deputy Chief Christopher Covelli.

A preliminary investigation shows a Ford Escort, driven by a 65-year-old Downers Grove woman, was stopped on Route 12.

The Ford was in the inside southbound lane due to a mechanical issue, Covelli said.

The Harley-Davidson struck the Ford, causing the motorcycle to roll over several times.

The driver and his passenger, Siano, were ejected from the motorcycle, Covelli said.

McHenry resident Kimberly Peil-Macdonald told Lake and McHenry County Scanner in an interview that she came upon the crash as she was leaving work.

Peil-Macdonald, along with a second bystander, used their vehicles to block the southbound lanes.

Peil-Macdonald, who is a nurse and used to work in fire/rescue, ran up to the scene with a trauma bag from her. She began providing aid to the male victim and was assisted by an off-duty police officer.

Bystanders realized there was a second victim, later identified as Siano, who had been thrown into the weeds along a guardrail.

Peil-Macdonald began performing CPR for approximately 10 minutes until paramedics arrived and took over care.

Peil-Macdonald said neither of the two victims, who were husband and wife, appeared to have been wearing helmets at the time of the crash.

Siano was transported to Advocate Condell Medical Center in Libertyville where she was pronounced dead, Covelli said.

The driver of the Harley-Davidson was also transported to Advocate Condell Medical Center where he remains in critical condition.

The driver of the Ford and her passenger, a 67-year-old Naperville woman, were uninjured.

The crash remains under investigation by the Lake County Sheriff’s Office Technical Crash Investigations Unit.
