20/20” asks: could someone ever forgive a mom who would abandon not one but three newborn babies within blocks of each other over a five year period? It is an incredible mystery that is solved right before viewers’ eyes as “20/20” teams up with renowned DNA detective and genetic genealogist CeCe Moore.

He's hired three private investigators hoping to find his biological mother and get those answers. All led to dead ends. Until now. Detective Cece Moore is part of his new team which was profiled in Friday's 20/20.

“It's definitely time for him to turn to DNA testing,” Moore said. “It's given answers to many families. The databases have grown immensely.”

JACKSONVILLE, Fla. - It's been 11 years of wondering, searching and struggling for a man who calls himself Benjamin Kyle. For the last 11 years, BK didn't know his real identity. But now, the man who calls Jacksonville home knows his true identity...Alive, but lost in his amnesia, until he got help from genetic genealogist CeCe Moore. The methodology we used to solve the Benjamin Kyle case was actually developed for adoption searches. For people who wanted to ID their birth families. It's applicable to lost identity as well," Moore explained.

Moore and a team worked on BK's case for two and a half years, comparing his DNA to those in databases across the country. Along with information BK thought he remembered, Moore's team made the connection - when law enforcement couldn't.

CeCe Moore, a genetic genealogist who helped Fronczak with his case, said finding a second cousin match was "substantially better" than finding a third cousin match. A second cousin could unlock the mystery of Fronczak's true identity because his and Alan Fisch's parents could be first cousins and their grandparents could even be siblings.

Paul did get help from an unexpected source. He has been on the phone daily with Moore. She is the founder of The DNA Detectives. The company which has taken the point on the Fronczak case.

“My team and I have worked on this case every single day for the last year-and-a-half. It might have been just a few emails per day or 18 hours a day. It's been an incredibly long road with unbelievable twists and turns,” Moore said.

Moore and her team scoured all three of the major DNA data banks, including Ancestry.com, to look for a genetic match. A company named Family Tree DNA donated free genetic test kits so the team could pursue numerous leads. Most of them fizzled.

But a possible match found six months ago led to the East Coast. Team members cracked the puzzle days ago by building a time machine in a way.

A friend of a friend saw the post and contacted someone in a unique position to help: CeCe Moore, a genetic genealogist who does the DNA research for the popular PBS series “Finding Your Roots” with Henry Louis Gates Jr. and also consults on “Genealogy Roadshow.”

Moore lives in San Clemente and has a son a few years older than Kayla Tovo’s. She has a special place in her heart for foundlings like Kayla Tovo who have nothing to go on.

“DNA,” Moore says, “was the only way to solve this.”

MYSTERY SOLVED

When three half-siblings who were abandoned at birth – Janet, Julie and Dean – go searching for their biological mother, CeCe Moore connects the dots. On ABC 20/20 the genetic genealogist reveals that she found a DNA link from the woman who supposedly rescued Janet from an alleyway. “The woman is either your mother or aunt,” says Moore, in a typically shocking reveal. The three siblings, now adults, don’t understand why she would do that.

CeCe Moore knows family geneaology can reveal stories even more complicated than that of Janet, Julie and Dean. Moore has appeared on many TV shows and is a consultant on Finding Your Roots with Henry Louis Gates, Jr.
