A 23-year-old Bartlett man was going at least 90 mph early this morning when his motorcycle slammed into a car on Route 20 in Elgin, leaving him dead from massive head trauma, police said.
Alex Konieczski, of the 500 block of Horizon Drive, was pronounced dead at the scene of the crash. He was not wearing a helmet, Elgin Deputy Police Chief Cecil Smith said.
The crash occurred when Konieczski's 2008 Yamaha motorcycle collided with the rear of a Pontiac Grand Am about 2:25 a.m. in the eastbound lanes of Route 20 near Grace Street, police said.
The car's driver, Michael Porter, 38, of the 700 block of Highland Avenue in Elgin, was not injured but "shaken up" from the incident and taken to Provena St. Joseph's Hospital, police said.
The force of the impact broke the rear axle and the rear window of the car. That damage, combined with skid patterns at the scene, led investigators to believe Konieczski was traveling at high rate of speed.
"We're estimating it was at least 90 mph. It may have been even faster than that," Smith said. "(Porter) said all he saw was the lights come up behind him. He stayed in the left lane and the next thing he knew he was hit."
After impact, the chopper-style motorcycle slid down Route 20 another 300 feet toward the Liberty Street overpass.
Konieczski apparently had just left a nearby party, according to several party guests who drove to the crash scene to see what happened, Smith said. He could not say whether alcohol was a factor in the crash.
A phone message left at Konieczski's residence was not immediately returned.
Smith said Porter was arrested and charged for driving on a suspended license.
The Kane County Coroner's Office did not perform an autopsy because it was obvious Konieczski died of massive head trauma. The office is sending blood samples to a forensic lab for testing.
