A father has died days after his family’s van was hit by a wrong-way driver, killing his wife and four children, as they were leaving for vacation on Interstate 90 in McHenry County.

The incident happened around 2:11 a.m. Sunday on Interstate 90 near mile marker 33.5, which is west of Route 23, between Marengo and Hampshire.

The Hampshire Fire Protection District, Marengo Fire and Rescue Districts, Genoa-Kingston Fire Protection District and Pingree Grove Fire Protection District responded to the scene with the Illinois State Police.

A gray 2010 Acura TSX was traveling eastbound in the westbound lanes for unknown reasons, state police said.

The Acura struck the Chevrolet head-on. Both vehicles became fully engulfed in flames.

A medical helicopter landed on the interstate at the crash scene.

Colleagues of Lauren Dobosz created a GoFundMe account Monday to raise money for Thomas Dobosz, the sole survivor of the family.

The Dobosz children included Emma, Lucas, Nicholas and Ella. The fifth child in the van was one of the kids’ friends, Kat.

“Lauren always made a great impression on everyone she met, she was full of life, laughter, and always a good time,” Lisa Torres said.

“We’re going to miss you Lauren and your spunky, sweet, sassy kids. We shall shine bright this year,” Torres said.

The fundraiser has collected over $95,000 in two days.

A relative of the Dobosz family said the family was headed on vacation when the crash occurred.

All westbound lanes of Interstate 90 near milepost 33 were closed for an investigation. Traffic was diverted off at Anthony Road.
