Edgar Davidson was accused of the murder by his first wife, who spoke with The Keepers interviewers under the condition of anonymity at a niece's behest. After Edgar, who had abused the wife and displayed erratic behavior in the past, arrived home covered in blood on the night of Cathy's disappearance, she immediately suspected him.
At Christmas that year, Ed gave the wife a wedding bell necklace inlaid with a stone that was not her birthstone, which his family now believes was the engagement present that Sister Cathy was out buying for her sister on the night of her disappearance. (Cathy's sister has since stated that the birthstone in the necklace fits her now-husband's birth month.)
It seems that Edgar actively encouraged his wife's suspicions, chuckling and making odd comments while the news broadcast about Cathy's disappearance played on TV. Davidson also drove a car with both feet, which lines up with the fact that there was mud found only on the left pedal in Cathy's car, which was found abandoned after her abduction and is presumed to have been driven by somebody involved in the crime. Davidson also called in to a radio show after the murder to say that he knew where Cathy's rosary was. Not to mention the man's criminal record, which includes car theft and cruising around middle schools attempting to lure girls into his car.
Because Edgar is still alive, The Keepers filmmakers caught up with him to ask a few questions about his potential involvement. Though he corroborated several aspects of the crime on camera, Edgar maintains that he did not kill Cathy Cesnik. Whether the now-elderly man still has his faculties about him is also in question; many Reddit and Facebook viewers expressed discomfort while watching his interviews due to the fact that Edgar seems "not all there."
