SALT LAKE CITY, UTAH- DNA testing found a girl born to a couple who used a fertility clinic is a genetic mismatch to her parents. Her father provided the sperm to the clinic.
Now, the University of Utah is investigating a complaint that a convicted felon working at the fertility clinic may have swapped out the father's sperm with his own 21-years ago.
The mother of the girl says her family was able to trace the daughter's lineage to a now-dead fertility clinic worker with help from his relatives.
Pamela Branum says she believes Thomas Ray Lippert made victims of other couples who went to the same clinic.
The University of Utah admits there is credible evidence of semen tampering.
The school opened a hotline and will offer paternity testing to anyone who used the clinic between 1988 and 1993.
