The wife of an Ohio National Guardsman charged with sexually abusing his adopted daughters and stepdaughters says she never saw signs of such abuse in the home.

The woman testified that one of the girls once threatened to make an allegation of sex abuse if her phone was taken away.

The defendant's wife also said Wednesday that another one of the girls was abused in an orphanage before she was adopted.

The woman is charged with intimidation and obstruction but not abuse. She pleaded not guilty. Her attorney has declined to comment while the case is pending.

The 42-year-old guardsman has pleaded not guilty to accusations of abusing girls who were under 13.

The Associated Press isn't naming the couple to protect the children's identities.
