After an exhumation showed Shele Danishefsky Covlin was strangled to death on New Year's Eve, cops are planning to arrest her estranged husband for her murder. Her death, initially thought to be caused by an accidental slip in the bathtub, came a day before she was allegedly planning to remove husband Rod Covlin from her will. A friend of Shele's told the Post she told him "more than once that 'he threatened to kill me.'" Rod Colvin reportedly had no response when a reporter asked him if he killed his wife, and cops plan to arrest the chairman of the US Backgammon Federation later this week.
