One person was killed and three were injured Sunday night in a crash on Hainesville Road in Round Lake Park, police said.
Two vehicles were traveling south on Hainesville Road when the crash took place at 9:10 p.m. The impact of the crash caused two vehicles to leave the road. A third vehicle involved had minor damage.
Three people were taken to Advocate Condell Medical Center in Libertyville, authorities said. Round Lake Park Police Chief George Filenko said a 55-year-old man from Round Lake Beach later died at the hospital.
Filenko said a driver of one of the vehicles ran from the scene after the crash.
Lake County Sheriff's Sgt. Sara Balmes said dogs from the sheriff's office and Round Lake Beach police came in to track the driver. Diesel, a sheriff's dog, tracked the driver for nearly a mile before locating him in the 700 block of WaterView Lane.
Filenko said Monday afternoon the driver has not been charged.
Lake County Coroner Howard Cooper said the autopsy was completed Monday, but he will not be able to release the victim's identification until Tuesday.
The crash remains under investigation by the Round Lake Park Police Department, the Major Crash Investigations Team, the Lake County state's attorney's office and the coroner's office.
