An unmarried biological father is not entitled to notice of an adoption proceeding, nor is the consent of an unmarried biological father required in connection with an adoption proceeding, in cases where it is shown that the child who is the subject of the proceeding was conceived as a result of conduct that constitutes a sexual offense under Title 76, Chapter 5, Part 4, Sexual Offenses, or under the laws of the state where the child was conceived, regardless of whether the unmarried biological father is formally charged with or convicted of a criminal offense.
