A Lake County grand jury on Wednesday approved additional counts of reckless homicide against a Long Grove man accused of being intoxicated during a crash that killed a woman in September.
Stephen E. Tomczyk, 22, of the 3200 block of Middlesax Drive, was already facing three counts of reckless homicide for the crash that killed Jeewon Kim, 47, of Buffalo Grove on Sept. 5, 2013.
With the charges added Wednesday, Tomczyk now faces six total counts of reckless homicide.
Cynthia Trujillo Vargas, communication manager for the Lake County States Attorney's Office, would not release details involving the new charges. Vargas said prosecutors would explain the added counts during Tomczyk's arraignment hearing Thursday in front of Judge Mark Levitt.
Tomczyk also faces three counts of aggravated DUI resulting in death and three counts of aggravated DUI resulting in great bodily harm.
His trial is scheduled for March 3, and he remains held in Lake County jail on $500,000 bail.
Authorities said Tomczyk's 2007 Ford F-150 collided with Kim's 2011 blue Honda CRV about 6 p.m. at the intersection of Westmoreland Drive and Route 83 in Hawthorn Woods.
Kim was pronounced dead at the scene of the crash, while her 16-year-old daughter -- a passenger in the Honda -- was taken to Advocate Condell Medical Center with life-threatening injuries.
The daughter survived the crash, authorities said.
Tomczyk appeared in court Wednesday before the grand jury indictments and prosecutors filed a motion to revoke a previous probation sentence Tomczyk was serving.
According to court records, Tomczyk pleaded guilty to possession of a controlled substance and was sentenced to 180 days in jail and 24 months of probation in May 2012. However, court records also show he violated the terms of that probation in April 2013, and was resentenced to an additional 120 days in jail and an additional year of probation.
If found guilty of the new charges, he could be sentenced up to 30 years in prison.
