A 13-year-old girl was one of two people who were killed Saturday in a crash in north suburban Round Lake Beach.

The girl was in the passenger seat of an orange 2006 Pontiac G6 about 7:30 p.m. when the car went flying into a condominium building in the 1500 block of West Crystal Rock Court, Round Lake Beach Police Chief Mike Scott said.

The girl, a Round Lake Beach resident, and the driver, a 34-year-old man from Chicago, were both rushed to Condell Medical Center in Libertyville where they succumbed to their injuries, Scott said.

A witness told Round Lake Beach police that the Pontiac was speeding in a 25 mph zone on Long Lake Drive prior to the crash, Scott said. Two units in the condominium building were damaged but no one was home when the car crashed into them.

Autopsies are scheduled for Aug. 26.
