A second man has died from his injuries after a crash caused by a wrong-way driver in Arlington Heights on Monday.
Anatoliy Elkind, 48, of Vernon Hills died at 5:07 p.m. Wednesday, said Arlington Heights Police Capt. Andrew Whowell.
Elkind was critically injured in the five-car crash on Rand Road near Thomas on Monday afternoon. He was being treated in the ICU at Advocate Condell Medical Center in Libertyville.
Police say the crash was caused by Stanley Ksiazek, 51, of Palatine, who was speeding in the wrong lanes of traffic.
Ksiazek's red pickup truck hit four cars -- a 2011 Volkswagen Golf, a 2002 Honda Civic, a 2001 Toyota Sienna and a 2013 Hyundai Elantra -- before leaving the roadway and flipping over.
Ksiazek died from his injuries Monday.
Two other people were hospitalized in the crash with injuries that were not life-threatening.
Police have said they do not suspect alcohol was involved in the crash. Whowell said police reached that conclusion because there was no strong odor of alcohol when Ksiazek was extricated from his vehicle or when he was treated at the hospital.
But a spokeswoman for the Cook County medical examiner's office said toxicology tests are being done to test for both alcohol and drugs in Ksiazek's system.
Results of toxicology tests can take three or four weeks.
Police have not yet said how fast they think Ksiazek was driving at the time of the accident but have said it was "excessive." Rand Road in that area has a 35 mph or 40 mph speed limit.
