WOODSTOCK – A Spring Grove-area man – charged with aggravated driving under the influence after a crash on June 26 that killed his passenger – had a blood-serum level of .150 when he was found in the woods near his vehicle, according to a search warrant obtained by the Northwest Herald.

Ryan Heineman, 33, was driving a Jeep early in the morning that crashed into a tree on Route 12, east of Sunset Road, police have said. The single-vehicle crash was discovered about 6 a.m. by a passing motorist.

His passenger, identified by the coroner's office as Tanya M. McDonough, also 33, was pronounced dead at the scene. The two were acquaintances, police have said.

Police have said that Heineman was located in the woods near his vehicle and was transported to the Northern Illinois Medical Center for his injuries, according to court documents. Police believed Heineman had injuries from his seatbelt, which left impressions on his chest.

When police located Heineman on Sunday morning, he was "muddy and disarranged," according to court documents. Investigators also alerted police that Heineman's blood-serum alcohol level was .150, which is nearly twice the legal limit of intoxication. However, some medical experts say a blood serum test could show higher results than what whole blood would show.

If convicted, Heineman could be sentenced to as many as 14 years in prison, which he would be required to serve at 85 percent, according to Truth in Sentencing guidelines.

Heineman is out on bond and will next appear in court July 11.
