A Utah couple discovered through a DNA test that their daughter, who was conceived through artificial insemination, does not carry the DNA of the man she has called daddy all her life.
The biological father was Thomas R Lippert, a convicted felon who worked as a technician at Reproductive Medical Technologies, the fertility clinic in Midvale, Utah. Lippert replaced clients’ sperm for with his own.
Before working at the clinic, Lippert served two years in prison for kidnapping a college co-ed for three weeks and using electroshock therapy on her to make her “fall in love with him,” KUTV reported.
The clinic is no longer open and Lippert died in 1999 at the age of 49. Authorities from the University of Utah, which had ties to the clinic, are involved in an ongoing investigation, but say Lippert could have switched his sperm in as many as 1,000 procedures.
