Police say a Deer Park teenager speeding crashed into another car, which killed an elderly man and left several people injured, on Lake Cook Road in Arlington Heights.
The Buffalo Grove Police Department, Buffalo Grove Fire Department, Arlington Heights Fire Department and Arlington Heights Police Department responded around 4:30 p.m. Saturday to the area of Lake Cook Road and Bloomington Avenue for a vehicle crash with injuries.
The Arlington Heights Police Department said a preliminary investigation showed a dark gray BMW M340i was traveling eastbound on Lake Cook Road at a speed higher than the legal limit.
A metallic brown Jeep Grand Cherokee was driving forward from a stop sign on Bloomington Avenue entering Lake Cook Road.
The BMW’s front end struck the Jeep’s driver’s side resulting in a T-bone-style crash, police said.
The force of the impact caused the Jeep to roll over several times and come to rest in the westbound parkway of Lake Cook Road.
There was significant intrusion into the Jeep’s driver’s side.
Police said paramedics removed the Jeep’s sole occupant, a 69-year-old Des Plaines man, and immediately began advanced life support treatment.
He suffered multiple traumatic injuries and was transported to Advocate Lutheran General Hospital in Park Ridge for treatment of life-threatening injuries.
He later died from his injuries just after 4 a.m. Sunday, police said.
The BMW driver, an 18-year-old Deer Park man, and two teenage passengers were evaluated by paramedics but refused transport to the hospital by ambulance.
They were picked up by family and self-transported for a medical evaluation.
A third teenage passenger in the BMW was transported by the Palatine Fire Department to a local hospital for a non-life-threatening injury, police said.
Lake Cook Road was shut down in both directions from east of Route 53 to Wilke Road for several hours while crash reconstruction investigators documented the scene and collected evidence.
The Arlington Heights Police Department said they are being assisted in the investigation by the Major Case Assistance Team – Serious Traffic Accident Reconstruction (STAR) Specialized Investigative Unit.
“Investigators will pursue legal process to access and obtain any electronic data stored within the involved vehicles in an effort to identify relevant contributory factors. The incident remains under investigation,” police officials said.
