Fertility Clinic Worker May Have Secretly Fathered Kids Woman discovers this felon is her dad, and more cases may follow By John Johnson, Newser Staff Posted Jan 10, 2014 6:20 PM CST 25 comments Comments (Shutterstock) (Newser) – An exceedingly creepy story out of Utah suggests that a male receptionist at a fertility clinic secretly swapped in his own sperm during treatments, fathering at least one child and probably more, reports LiveScience. Oh, and this receptionist just happened to be a convicted kidnapper who once held a woman captive and used electroshock therapy on her in a failed attempt to get her to fall for him, reports KUTV. He died in 1999, but all of this has now resulted in a website reaching out to other possible victims called Was Your Child Fathered by Thomas Lippert? The crazy story, first reported at a genealogist's blog, began unwinding when a couple and their 21-year-old daughter had their DNA tested as a lark via 23andMe. To their shock, they discovered that daughter and father weren't related. That made no sense because, while the couple had used the now-shuttered Reproductive Medical Technologies Inc. for help conceiving, the husband had given his own sperm to be used in the process. Further testing then revealed that the daughter's real biological father was Lippert, who had worked at the clinic in the late 1980s and into the 1990s. The wife recalls him having photos of babies at his desk, and she fears they were all fathered by him. The clinic was affiliated with the University of Utah, which has been conducting its own investigation, notes the Salt Lake Tribune.
