The family of a Warren County teen believe a medical condition caused her to crash her car Tuesday, sending her to the hospital in critical condition. Isabelle Meehan, 17, has Type 1 diabetes, they said. “She drove 20 minutes north of our house because she was so disoriented from her low blood sugar and she just kept driving because she didn’t know where she was,” her sister Abby said. The family says Isabelle was driving home from an ACT tutoring session on when she became disoriented, passed out and crashed on Montgomery Road north of Strout Road, near Morrow. She was ejected from her car.
