Two men were killed and a boy was injured in a traffic crash Saturday evening in northwest suburban Roselle, police said.

About 7:37 p.m., a motorcycle struck a car in the 1100 block of West Lake Street near Wheaton Road, Sgt. David Hourigan of the Roselle Police Department said.

Both the motorcycle driver, who was 19, and the other driver, who was 35, died on the scene. The motorcycle driver was identified as Brian Wojcik, and the car's driver was identified as David Phillips, according to DuPage County Coroner Dr. Richard Jorgensen.

Police said Wojcik, who was driving a 2007 Yamaha motorcycle, is from Bloomingdale and Phillips, who was driving a 2010 Chevrolet Malibu, is from Roselle.

Preliminary investigation showed the Malibu was leaving the Brunswick Zone bowling alley, 1100 W. Lake St., and trying to make a lefthand turn when the motorcycle, which was headed west, hit the car on its driver's side, authorities said.

Based on witness accounts, police believe the motorcycle was traveling at a high rate of speed when it struck the side of the passenger vehicle.

"We believe speed [was] a large contributing factor," Hourigan said

A 13-year-old passenger, believed to be the son of the 35-year-old man, was hurt and was taken to Advocate Good Samaritan Hospital. He was conscious and talking with first responders, and his injuries did not appear to be life-threatening, Hourigan said.

According to a press release Sunday from the Roselle Police Department, the crash is being investigated with the help of the DuPage County Accident Reconstruction Team and the county coroner is conducting toxicology tests to see if alcohol or drugs played a role in the crash.

If anyone witnessed the crash or has information about it, police ask that they contact Officer David Cotton by phone at (630) 671-4076 or by e-mail at dcotton@roselle.il.us.
