Brittani R. Yilmaz was pronounced dead at the scene.

A Millsboro woman was pronounced dead at the scene of a single-car crash Thursday night near Millsboro.

Brittani R. Yilmaz, 25, was a passenger in a 2016 Dodge Dart driven by 29-year-old James J. Lynn of Staten Island, New York, Delaware State Police spokesman Master Cpl. Gary Fournier said.

The crash took place at about 7:48 p.m. Thursday, Nov. 10 as the Dart was headed northbound on Harbeson Road. For unknown reasons, the car went off the east side of the road, through some grass and hit a utility pole. The Dart came to rest in the grass off the right side of the road, Fournier said.

Yilmaz died despite the fact she was wearing her seat belt, he said.

Lynn was treated for non-life-threatening injuries after being flown to the Christiana Medical Center.

He is charged with operation of a motor vehicle causing death of another person, failure to remain in a single lane, and failure to have insurance. He later was released after posting a $2,000 secured bond.

Speed does not appear to be a factor in this case and it is not known if drug or alcohol impairment were involved, Fournier said.

The investigation is continuing, he added.
