Dr. Donald Cline, 77, pleaded not guilty to two felony obstruction of justice charges for misleading authorities who were investigating complaints from two of the now-adult children against him.
Cline is accused of being the biological father of at least eight people, the youngest of which would be about 30.
The 77-year-old told six adults who believed they were his children that he had donated his own sperm about 50 times starting in the 1970s.
One of the adult children took a saliva-based DNA test through a private personal genomics company and found that she was related to at least eight other people in its database.
Cline used his own sperm whenever he didn’t have a donor sample available.
Cline’s attorney, Tracy Betz, released a statement saying he is not accused of hiding documents, influencing witnesses or otherwise not cooperating with the attorney general’s investigation.
Cline was released on his own recognizance.
