The vehicle involved in the crash was part of a group of church members headed to a retreat in Wisconsin. An 11-year-old boy also ejected from the vehicle remains in serious condition at Condell Medical Center in Libertyville. Two other adults taken to Vista Medical Center in Waukegan are also listed in serious condition.

Investigators say Sylvia Jacob, 50, lost control of the vehicle while trying to switch lanes. The two children in the back seat, who did not have seat belts on, were ejected from the rear window of the car. Ten-year-old Reeve Mathew was killed instantly when his head struck the concrete.

A total of seven people were in the vehicle, and none of the others suffered life-threatening injuries. After the crash, northbound I-94 remained closed for several hours while police investigated.

Meanwhile, church members are mourning the loss of a child.

"Reeve was a God-fearing child," said Deacon Jake Jacob, St. Mary's Knanaya Jacobite Syriac Orthodox Church. "He was only 10-years-old and actually, next week, he was planning to be an altar boy in the church, so he was planning for that and he was very active in the church."

Illinois State Police said Sylvia Jacob crossed four lanes of traffic before crashing into the median. Police have cited her with improper lane usage.

A memorial will be held at noon Sunday for Reeve at St. Mary's Church in Waukegan.
