(AP) — A 41-year-old Omaha man who sexually assaulted a teenager has been given 30 to 35 years in prison.

Ross Ohrt was sentenced on Wednesday. He’d pleaded no contest and was convicted of sexually assaulting a child and visual depiction of sexually explicit conduct.

Authorities say Ohrt had known the girl for several years and had worked out a barter system with her. He awarded her points toward gifts in exchange for her performing sexual acts or sending him explicit photos.
