A 26-year-old St. Charles man was killed Friday morning following a crash on Randall Road in Elgin, police said.
A second crash 90 minutes later about a half-mile on Randall left two others injured.
A preliminary investigation of the first crash shows a Yamaha motorcycle, driven by the St Charles man, was northbound at about 6:55 a.m. on Randall Road at Highland Avenue when it crashed into a BMW car that was turning onto eastbound Highland from southbound Randall, police said.
Witnesses told police before the crash the motorcyclist had been riding the shoulder and entered the intersection from a non-lane portion of the road.
The motorcyclist, who was wearing a helmet, was pronounced dead at Advocate Sherman Hospital in Elgin. His identity is being withheld pending notification to relatives.
The driver of the BMW, a 44-year-old man from Woodstock, was not injured.
A single lane of northbound Randall Road and all of eastbound Highland Avenue were closed for approximately 3½ hours while police investigated. The crash remains under investigation and anyone with information should call (847) 289-2661.
The second crash occurred about 8:30 a.m. on southbound Randall Road at Royal Boulevard. It involved three vehicles and left two people with minor injuries, Elgin Police Cmdr. Dan O'Shea said.
He said a vehicle attempted an illegal lane change which resulted in a chain reaction of rear-end crashes with two other vehicles.
The two injured people were taken to the hospital.
