A fourth man accused of paying a Nebraska mother to let him have sex with her 14-year-old daughter has been charged with sexual assault.

Prosecutors say 22-year-old Logan Roepke (REP-key), of McCook, had sex with the teen twice last year.

The mother is also accused of pimping out her 7-year-old daughter.

The Nebraska State Patrol says the 35-year-old mother allowed at least seven men to have sex with her teenage daughter at least 20 times. Investigators say at least three men had sex with the 7-year-old.

Roepke posted bond Tuesday. Attorney Aaron Bishop says Roepke plans to plead not guilty.

The mother is jailed on charges of child pornography and conspiracy to commit sexual assault of a child. The Associated Press is not using her name to protect her daughters.
