A 32-year-old man was killed in Harvard on Saturday after he drove off the road and rolled his truck over, causing him to be ejected from the vehicle, police said.

The McHenry County Sheriff’s Office, Harvard Police Department and Harvard Fire Protection District responded around 7:03 p.m. Saturday to the 20200 block of Route 173 in unincorporated Harvard for a single-vehicle crash with injuries.

McHenry County Sheriff Sgt. Aimee Knop said that a 2003 Ford F-250 pickup truck was traveling westbound on Route 173 east of Harvard Hills Road.

For unknown reasons, the Ford went into the eastbound lane of traffic and then back through the westbound lane of traffic before exiting the roadway to the north.

The vehicle rolled over multiple times. The sole occupant and driver of the truck, Gerardo Albarran-Juarez, 32, of Harvard, was pronounced dead at the scene by paramedics, Knop said.

The airbags in the truck did not deploy and Albarran-Juarez was not wearing a wearing seatbelt, Knop said.

The roadway was closed in both directions for 3 ½ hours while accident investigators conducted an extensive investigation.

Toxicology reports are pending. The crash remains under investigation by the McHenry County Sheriff’s Office Major Crash Investigation Unit and the McHenry County Coroner’s Office.
