LAS VEGAS (KLAS) -- A teenager’s online DNA test led her family to file a lawsuit Monday against a Las Vegas fertility clinic, alleging the wrong embryo was implanted in her mother 18 years ago and the parents who raised her are not biologically related to her, the 8 News Now Investigators have learned. Until 2023, the teenager’s parents believed their daughter was the result of in vitro fertilization -- an embryo created, in this case, from the father’s sperm and a donor egg, the lawsuit said. An Ancestry.com DNA test showed the teenager’s parents are not biologically related to her. “My client had more tears than I've ever seen someone shed, because what he thought was his daughter -- isn't,” attorney Robert Murdock said. Murdock filed the lawsuit Monday in Clark County District Court. The teenager’s mother died in 2022 before her daughter took the test. Murdock spoke with the 8 News Now Investigators on behalf of the daughter and her father. In 2004, the couple sought help in conceiving a child from the now-closed Nevada Fertility C.A.R.E.S., Murdock said.

It's an amazing thing.” According to the lawsuit, the couple chose an egg donor based in Arizona to combine with the father’s sperm to have a child. “This was a way to have his heritage move on and it turns out it's not and it's a little too late for that,” Murdock said. According to the lawsuit, the DNA result showed that neither the teenager’s father’s sperm nor the donor egg were implanted in the mother. Instead, the implant embryo came from another Las Vegas couple, the lawsuit said.

The lawsuit names the doctor and the embryologist who reportedly worked with the family. Both the doctor and embryologist remain working in the IVF industry, the lawsuit said.

The lawsuit cites negligence and malpractice and demands a jury decide any culpability and potential damages.
