Sherry Allender, 22, and Charles J. Jones, Jr., 27, were accused of using duct tape to wrap the hands, legs and feet of the child while recording their actions on a cellphone April 17, the Dayton (Ohio) Daily News reported.
Allender pleaded guilty to complicity to commit abduction and complicity to commit child endangering. Jones pleaded guilty to abduction and child endangering.
The daughter was not seriously hurt but she was clearly in pain in the cellphone video, particularly when Jones ripped the tape off her mouth, causing her to scream in agony, Montgomery County Prosecutor Mathias H. Heck Jr., said.
Heck said Allender and Jones could be heard laughing on the cellphone recording.
After the taping incident, Allender and Jones sold the cellphone to the girl's biological father, whose mother discovered the video on the phone and called police in May, the Daily News reported.
