On February 28, 1972, three young sisters in Spencer, Massachusetts — 4-year-old Cynthia Lovett, 6-year-old Margo Lovett, and 2-year-old Holly Lovett — were found dead from gunshot wounds. The killings of the Lovett girls devastated their small town and prompted a police investigation into the triple homicide.

There are no identified arrests or named suspects in connection with the murders in the records consulted, and few details about the investigation have been released. The deaths of Cynthia, Margo, and Holly remain unresolved.
