Melodie Stankiewicz, 27 and originally from Cambridge, Massachusetts, was found floating in Captain’s Pond in Salem, New Hampshire, on June 30, 1975. Authorities determined her death was a homicide: she had been stabbed 23 times in the chest and abdomen, injuries described as the product of an intensely violent attack.

The original investigation produced no arrests and the case grew cold. In September 2008 Boston-area prosecutors reopened the inquiry and re-examined her murder alongside the unsolved killings of Holly Davidson and Kathy Williams because of reported similarities. That review focused on Leonard Paradiso, a convicted murderer and suspected serial killer who operated in the Boston area during the same period, but investigators did not develop enough evidence to charge him in Melodie’s death.

Her murder remains unsolved and is listed as an active investigation with New Hampshire’s Cold Case Unit. Does anyone who lived in the Salem or Cambridge area in 1975 have information that could help investigators?
