Investigating Sheridan Peterson is a legitimate undertaking. After all, he has been investigated twice by the FBI and he appeared on the HC docu where he seemed proud to be a key suspect.
However, doing a thorough investigation properly is a bit tricky, I agree. As far as I can tell, Eric has used discernment, sound judgment and tact in his approach to Sheridan and his family.
Remember, Sheridan went ballistic when I interviewed his brother and then wrote about it.
Also, when I interviewed some of Sheridan's former neighbors in the Windsor senior living community, one woman seemed genuinely afraid of Sheridan. She told me she was convinced that Sheridan killed his wife. So, imo inquiring into Sheridan's life often requires some strong digging.
