Dagmar Overbye ran a foundling center in Copenhagen from 1916 to 1920. It was supposedly a place where unmarried mothers could take their infants to be adopted, although they had to pay a fee for the infant to be accepted. The unsavory business of hiding the scandals of others was something few talked about, and Overbye operated under the radar for several years. It is unclear how well records of the babies she took in were kept, if at all. The parents who paid Overbye to take care of matters rarely even spoke of it, much less went back to check on their babies. One woman finally did.
Karoline Aagesen placed her newborn daughter with Overbye in 1920 and immediately regretted her decision. Aagesen went back to retrieve her child the next day, but Overbye told her the baby had already been adopted, by a couple whose address she couldn’t recall. Aagesen went to the police, who investigated Overbye and the “adoption agency” she ran out of her apartment. They found baby clothes and charred bones in the stove. Overbye was arrested and confessed to killing either 16 or 20 babies, reports vary. However, from the evidence found, she was convicted of only nine murders. The babies had been strangled, drowned, or burned, and some bodies were found in her loft and buried underground in addition to the evidence from the stove. More parents came forward after Overbye’s arrest, and estimates of the number of infants she may have killed range from 29 to 180. It is believed that the first child Overbye killed was her own, born a few years before she opened her baby business. She was sentenced to death in 1921, which was commuted to life, and she died in prison in 1929.
