An underage stepson is expected to recall the harrowing details of allegedly being exploited by his stepmother.
The teenage boy, 15, is expected to be deposed and asked about the details of the incident, where his stepmother was caught committing vulgar acts with him.
The incident in question took place last year when the boy was visiting his biological father, Frank Von Yates, and stepmom, Alexis Von Yates, in Ocala, Florida.
