The Corolla Wild Horse Fund is seeking a new chief executive officer after its former executive resigned suddenly.

The fund manages a herd of approximately 120 wild horses that roam more than 7,000 acres on the northernmost Currituck Outer Banks of North Carolina.

In a written statement, the organization’s board of directors said it will begin its search for a new chief executive officer at the beginning of 2018. The search begins after former director Linda Adkins resigned six months after being appointed to the position.

“The fund is not able to release any other details regarding any confidential personnel matters,” the statement said
