In the quiet suburban town of Millbrook, Connecticut, the phrase “family secret” usually refers to a hidden inheritance or a forgotten affair. But for the Thompsons—a well-respected family of physicians and philanthropists—the secret was a living, breathing person.
But that was the official story. The truth, as uncovered by investigative journalist Mara Huston in her new podcast The Stand-In Child , is far more chilling.
Neither woman knew the other existed until a 23andMe test taken by a curious cousin flagged a “parental discrepancy.” Sarah, seeking her biological roots, matched not with the Delgado lineage, but with a woman in Connecticut who had given up a baby for adoption in 2001 due to a heart condition.
The phrase “the other family” haunts this case. For the Thompsons, Sarah is a ghost—a mistake erased by money. For the Delgados, Emily is a fantasy, a daughter who might have been. For the women themselves, the swap created two parallel lives running on stolen tracks.
Meanwhile, the Delgados—desperate after years of failed IVF—were on the list for any available infant. The agency’s director, now deceased, offered a solution: swap the paperwork. Give the “perfect” baby (Baby B, later named Sarah) to the Thompsons, and place the baby with the murmur with the Delgados, who “wouldn’t know the difference.”
