April 23, 1887 - Dagmar Overby

Dagmar Johanne Amalie Overbye (Danish: [ˈtɑwmɑ ˈɒwɐˌpyˀ]; 23 April 1887 – 6 May 1929) was a Danish serial killer. She murdered between nine and 25 children, including one of her own, during a seven-year period from 1913 to 1920.

Overbye was working as a professional child caretaker, caring for babies born outside of marriage, and murdering her own charges. She strangled them, drowned them, or burned them to death in her masonry heater. The corpses were either cremated, buried, or hidden in the loft.

Overbye was convicted of nine murders as there was insufficient proof of the others.
