A 15-year-old boy was killed in a crash involving an Illinois Department of Transportation snowplow that injured two other people early Friday in south suburban South Holland.

Troopers responded to the crash between the plow and another vehicle at 2:41 a.m. at Woodlawn Avenue and 162nd Place in South Holland, according to Illinois State Police.

Three people, including the plow’s driver, were taken to hospitals after the crash, state police said. Further details were not immediately available.

Chauncey Tucker, 15, was pronounced dead at 4:19 a.m. at Ingalls Memorial Hospital in Harvey, according to the Cook County Medical Examiner’s Office. An autopsy Saturday found he died of multiple injuries from the crash and his death was ruled an accident.

Detectives were investigating whether alcohol was a factor in the crash, state police said.
