Lancaster County Judge Mary Doyle on Tuesday set Grafe's bond at 10 percent of $75,000 and ordered him not to have contact with any children younger than 16. Prosecutor Matt Acton asked for a $250,000 bond. Grafe’s attorney, Bob Creager, said his client is a lifelong Nebraska resident and argued for a $40,000 bond.

Grafe made bail Tuesday; Chandler and Rahe were released Friday after posting $25,000 each.

Grafe's arrest and arraignment are the most recent developments in a case that started late last month when an unidentified informant tipped off a state trooper to nude photos of the girls allegedly texted to him by the Upland woman.

The patrol set up a sting, and the mother was arrested April 26 after she allegedly agreed to prostitute her older daughter for $200 to an undercover investigator in a Kearney motel.

She was charged with conspiring to commit sexual assault of a child and child pornography. She is in the Buffalo County Jail on a full $250,000 bond.

The Journal Star has chosen not to name the woman in order to protect the identity of her daughters.

Buffalo County Attorney Shawn Eatherton said he didn't know why a mother would put her daughters in such a position, but that any motive is irrelevant.
