A 51-year-old town resident was charged last week with reckless driving for causing a four-car crash in late October that severely injured an 18-year-old Stamford man, according to New Canaan Police Sgt. Carol Ogrinc.

Carol Sung, of New Canaan, turned herself in last Thursday on a warrant on the charge and was released on a $500 bond, according to Ogrinc.

A review of the event recorder of the 2010 Chevy Tahoe Sung was driving indicated she was going more than twice the 30 mph speed limit heading west on Silvermine Road when she rear-ended a BMW in front of her belonging to local cab business Hoyt's Livery.

That car then crossed the road and struck an oncoming Subaru driven by the 18-year-old man. The teen remained in critical condition for days after the crash, and remained in Yale-New Haven Hospital until Nov. 19, when he was released. Interviewed in January at a ceremony honoring the firefighters who rescued him, the badly injured man, Michael Bivona Jr., said he could not recall the accident.

The Oct. 30 crash occurred at around 5:30 p.m., when Sung's vehicle struck the BMW from behind while heading west on Silvermine Road. The BMW then struck the teen's vehicle head on as well as the car of a 41-year-old Wilton woman, both of which were traveling east.

Firefighters used cutting tools to remove Bivona Jr., who was badly pinned in the heavily damaged compact car, according to fire officials.

Ogrinc could not provide additional detail about why Sung's car was driving so fast, and the police department referred a request for the warrant to the State's Attorney's

Office in Superior

Court in Norwalk.

When police arrived, Sung's vehicle was rolled on its side on the westbound side of the road in the woods, and all three other cars were seriously damaged.

The 50-year-old Norwalk man driving the livery car and the 41-year-old Wilton woman were both treated for non-life-threatening injuries at local hospitals. Their names have not been released.

Sung is scheduled to appear in state Superior Court in Norwalk on March 31, according to Ogrinc.
