Kevin and Niky Mazur, and their children Teegan, 3, and Bryce, 1.

Over $75,000 has been raised for the family of the grandmother and her 1-year-old grandson that were killed in a crash in Lake Villa that also left the woman’s 3-year-old granddaughter fighting for her life.

Nancy Siedlecki, 64, of Spring Grove, and her 17-month-old grandson Bryce Mazur, who lived in Lake Zurich, were both pronounced dead at the scene of the Thursday crash, Lake County Coroner Dr. Howard Cooper said. An autopsy confirmed they died of multiple blunt force trauma injuries.

The three-vehicle crash occurred around 5:20 p.m. Thursday near North Route 59 and Beach Avenue in unincorporated Lake Villa.

Lake County Sheriff Spokesman Sgt. Christopher Covelli said that a 2017 Nissan SUV, driven by Siedlecki, was traveling northbound when it struck a 2014 Ford pickup truck that tried to merge back out onto the roadway from the shoulder.

The Nissan rolled over onto its side and was then struck by a southbound 2007 Hyundai minivan. Siedlecki and her 17-month-old grandson, who was in the backseat of the car, were both pronounced dead at the scene, Cooper said.

A Flight For Life medical helicopter transported Siedlecki’s 3-year-old granddaughter Teegan Mazur, who was also in the backseat of the Nissan, to Advocate Lutheran General Hospital in Park Ridge where she remains in a medically induced coma.

A 57-year-old man and a 15-year-old boy, both from Lake Villa, who were in the Hyundai minivan, suffered serious but non-life-threatening injuries and were transported by ambulance to Advocate Condell Medical Center in Libertyville. Both of them have since been released from the hospital.

The 41-year-old Grayslake man driving the Ford pickup truck, which was pulling a trailer, suffered non-life-threatening injuries and was also transported by ambulance to Advocate Condell Medical Center. He has also been released from the hospital.

A GoFundMe page created by co-workers and close friends of the family has raised nearly $40,000 as of Sunday evening. A second GoFundMe, also created by a co-worker of the 1-year-old boy’s father, has raised $35,000 as of Sunday evening, bringing the total amount raised to $75,000.

“Our dear friends, Niky and Kevin Mazur were impacted by a life-altering tragedy. What should’ve been a joyous time of the year quickly turned into the most challenging time of their lives,” the GoFundMe page said.

“Heaven has gained two angels, Nancy was Niky’s best friend, and Bryce was Kevin and Niky’s buddy. Little Teegan is proving by the second how mighty she is, resiliently fighting for her life and making progress that can only be explained as a miracle.”

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