A 19-year-old woman has died and a 16-year-old girl remains in critical condition on life support following a crash between a BMW and a dump truck in Wauconda on Friday.

The Wauconda Police Department and Wauconda Fire District responded around 1:35 p.m. Friday to the area of Route 12 south of Case Road for a vehicle crash with injuries.

A red BMW 325i and a blue Mack dump truck pulling a trailer with a bulldozer were involved in the crash, according to Wauconda Police Department Public Information Officer Heather Cognac.

A preliminary investigation showed that the Mack dump truck was pulling out from a private drive in the 29000 block of Route 12.

Cognac said that the driver of the BMW, for unknown reasons, crashed into the rear of the Mack truck and trailer at a high rate of speed, witnesses reported to police.

Lake County Coroner Dr. Howard Cooper told Lake and McHenry County Scanner on Tuesday that the 19-year-old woman later died at the hospital. Her identity is expected to be released on Wednesday.
