Ross accompanied the girl and her mother to the appointment, but allegedly tried to flee after they found out she was pregnant, Brewer said.
"At that time, Ross gets up and runs out of the doctor's office," Brewer said. Ross was later found and arrested near Castle Hayne.
Ross had dated the girl's mother for several years. The girl told law enforcement he sexually abused her, according to Brewer.
The Pender County Sheriff's Office initially responded to the scene, and notified the New Hanover County's Sheriff's Office because the family had recently moved to New Hanover County.
The charges Ross is facing in Pender County stem from allegations in the months leading up to July 2020, said James Rowell, the commander of the civil division of the Pender County Sheriff's Office.
