SCOTT, Wis. (AP) -- A medical examiner says two teenage girls died of accidental drowning when their car flipped over into a creek in Brown County.

Brown County Medical Examiner Al Klimek says Paige Derenne was driving the car that went off the road and overturned in the creek Monday.

Both Derenne and her friend, Gabrielle Fritsche, were sophomores at Green Bay Preble High School. The two 16-year-olds from Scott were pronounced dead at a hospital.

The Green Bay Press-Gazette reports both deaths were drownings and were ruled accidental. The medical examiner says the girls had their organs donated.

Klimek says it's unlikely Derenne had any alcohol in her system. A toxicology report is expected in seven to 10 days.
