Samantha says her husband, Zachary, began behaving out of character about two years ago when she claims he started showing signs of delusional thinking and paranoia. She says that not only has he falsely accused her of cheating on him with over 170 people but that he has also alleged she’s been paid thousands of dollars for allowing unnecessary medical procedures to be performed on their infant son. Zachary says he believes it’s Samantha who changed, not him but admits that their son is sick, “scientifically speaking.” He insists that Samantha has cheated on him numerous times with his co-workers, family members, and three U.S. Presidents. In the video above, Dr. Phil asks Zachary, “Wouldn’t it be a huge relief if you found out ‘Phew! I was wrong?’” Zachary replies, “Yeah. Absolutely. But at the same time, I just screwed everything up then.” Dr. Phil introduces Zachary to Dr. Charles Sophy, a psychiatrist and retired Medical Director for the County of Los Angeles Department of Children and Family Services. What is Zachary’s response when Dr. Sophy asks him about his history with alcohol and prescription medication?
