Four people were seriously injured, some of whom were ejected from the car, during an overnight roll-over crash in unincorporated Woodstock, authorities said.

Alex Vucha, Communication Specialist with the Woodstock Fire/Rescue District, said firefighters were dispatched to the 11200 block of Charles Road at 2:07 a.m. for a report of a single-vehicle crash with unknown injuries.

Firefighters arrived within six minutes and observed a single-vehicle rollover crash where two occupants appeared to have been ejected.

He said one occupant remained entrapped, and one occupant had self-extricated from the vehicle.

Paramedics quickly began assessing all four occupants to determine the severity of their injuries, Vucha said.

Firefighters extricated the trapped passenger within four minutes and began medical treatment, Vucha said.

Four medical helicopters were requested, Vucha said, but all declined due to overnight weather conditions.
