James Seward, 18, Kelly Cronin, 18, and Promise Williamsen, 18, killed in single-vehicle crash on Lily Lake Road in McHenry, Illinois

(CBS) – Three teenagers were killed Friday afternoon in a single-vehicle crash in the far northwest suburbs, the McHenry County coroner announced. The McHenry County Sheriff’s Department was investigating the crash. A third occupant of the vehicle, an 18-year-old female, was transported to Centegra McHenry Medical Center, where she was pronounced dead shortly before 4 p.m. The driver, an 18-year-old male, and a passenger, an 18-year-old female, were pronounced dead at the scene, Coroner Anne Majewski said in a news release. Authorities responded around 2 p.m. to a call of an accident at 1308 S. Lily Lake Road in unincorporated McHenry.

Two of the three 18-year-olds who died in a car crash Friday in McHenry County are being remembered for their passion for working on and souping up trucks -- a passion that ended too soon. Arnold said Seward "lived and breathed" automotive and was very knowledgeable in the repair shop, despite his young age. McHenry County College's Facebook page posted a message sending thoughts and prayers to the family and friends of Williamsen and the other victims. Williamsen was taking automotive classes at McHenry County College, according to her Facebook page, which includes photos of her working on her Chevrolet truck and posing in front of her 1994 Chevrolet Camaro. Seward went to school to be a technician and got his first job at Arnold's repair shop six months ago.

Services have been set for three teens who died Friday in a fiery car crash in McHenry County. The accident killed Kelly Cronin of Island Lake, James D. Seward of McHenry and Promise Williamsen of McHenry. The three friends were killed in a single-car crash in Nunda Township. The car in which they were riding went off South Lily Lake Road after a curve, hit trees and caught fire, authorities said. Seward worked at a McHenry repair shop, while Williamsen was taking automotive classes at McHenry County College, according to her Facebook page.
