When reached later Tuesday by CNN, Eva Cameron said, "We understand she lost her ID card and that's how the situation has turned into what happened. She's already an adult. I just have to leave it at that."

Eva Cameron would not answer further questions.

Authorities took Lynn Cameron to a hospital, where she was discovered to have only a basic vocabulary of 30-40 words, according to Smith.

A Campbell County Chancery Court order in the case described Lynn as a "severely disabled adult, suffering from profound mental deficits, and is unable to care for herself or her personal needs."

According to the court, the mother stated, "She could not and would not care for Lynn Cameron."

Eva Cameron said that she has another disabled child and that caring for both was too much to handle, according to the Northwest Herald.

Authorities said Lynn Cameron is being cared for at a facility in Roane County.

When asked how the young woman is doing, Smith replied, "Lynn is doing fantastic."
