Authorities say a Utah mom has plead guilty for taking nude pictures of her 13-year-old daughter so that she could text them to an older man.

The Deseret News reports that the 35-year-old Duchesne County woman took the photos because her daughter didn't know how to use the camera on an Iphone.

Court documents show that the 31-year-old Daniel Dean Divine had sent the teenager the phone and asked her to send him nude photos.

The mother told investigators that her daughter and the man planned to wait until she was 18 to begin a sexual relationship.

She plead guilty Thursday to child abuse. Divine is in jail on charges of sexual exploitation of a minor.

The mother's name is being withheld to protect the identity of her daughter.
