NAPERVILLE, Ill. (STMW) – Five young adults were taken to hospitals, including three in critical condition, after the sport-utility vehicle they were inside hit a tree Saturday night in west suburban Naperville.

At 7:45 p.m. an SUV was westbound on 75th Street when the driver lost control and the SUV hit a tree near Washington Street, said Naperville Fire Capt. Rick Zakaras. The speed limit on 75th Street, which is a divided highway in a non-residential area, is 50 mph.

Five ambulances, two engine companies, a heavy rescue unit, a truck company and two staff vehicles got to the scene at 7:53 p.m. and found one person outside the vehicle walking around and four trapped inside it, the captain said.

The four were cut out of the SUV and all five were taken to Edward Hospital in Naperville, three in critical condition and two who were less seriously injured, the captain said.

The hospitalized are possibly all in their late teens, and were not family members, according to Zakaras.

Zakaras said he did not know what caused the SUV to lose control and he did not know what the condition of the road was at that time.

Naperville police were not immediately available.
