Motorcyclist dies after three-vehicle crash in Arlington Heights

A motorcyclist was killed Tuesday night in a three-vehicle crash on the border of Arlington Heights and Mount Prospect.

Arlington Heights police said the crash happened at about 6:30 p.m. as the motorcyclist riding a 2017 Harley Davidson and a Hyundai Elantra were westbound on Northwest Highway approaching South Waterman Avenue. The two vehicles were struck by a 16-year-old driving a Hyundai Genesis coupe turning left from Waterman onto Northwest Highway.

Attempts to resuscitate the motorcyclist were unsuccessful and he was pronounced dead at the scene.

The Cook County medical examiner’s office Wednesday identified the motorcyclist as 44-year-old Sean F. O’Brien. An autopsy determined he died from multiple blunt force injuries sustained in the crash.

The 16-year-old driver was cited for failure to yield the right of way while turning left and failure to reduce speed to avoid an accident. An initial court date has been slated for Nov. 21.

Police were able to exclude alcohol or drug impairment by the 16-year-old driver.

The crash closed the intersection for several hours, police said.
