Anne Psaradelis was 15 when she and her friend, also 15, left Merrimack, New Hampshire, on July 11, 1973, saying they would go swimming and stay at each other’s houses. Instead the girls went to Hampton Beach and were last seen late afternoon July 12, reportedly hitchhiking toward their hometown. Their parents reported them missing the next day when they did not return.

On September 29, 1973 a hunter found the badly decomposed bodies of Anne Psaradelis and Diane Compagna in woods off New Boston Road in Candia, a short distance from Route 101. The advanced decomposition prevented an official determination of cause of death, though investigators have long believed the girls were strangled. Police once questioned a suspect after learning one girl had allegedly been sexually assaulted before the disappearance, but no charges were filed.

The double homicide remains unsolved with no arrests. A retired Merrimack detective, Joseph Horak, later named a man he believes committed the murders in books he published, but the official investigation is cold and unresolved.
