Alfred W. Ruf, 71, copped to lacing his spouse’s drink roughly a dozen times in Richmond in late 2021 as part of the twisted plan to run off with his stepdaughter, Fox 59 reported. Ruf, who pleaded guilty in Wayne County Court on Monday, told cops his stepdaughter and one of her friends had allegedly convinced him to go ahead with the plot and provided him with the drugs to sprinkle in his wife’s drinks. He claimed his wife’s daughter wanted to “get mom out of the picture” so they could cash in on her life insurance policy — and she had promised to marry him after they “took care of” the wife, according to court documents. The husband admitted to poisoning his wife’s drink about 12 different times between September and December 2021.
