The 57-year-old murder of a little girl in Pennsylvania has finally been solved, 

thanks to the assistance of a teenager genealogist.

Marise Chiverella's murder on March 18, 1964, remained unsolved for 57 years.

In 2007, Pennsylvania's state DNA lab was able to build a profile

of the suspect from semen left on Chiverella's jacket. 

A year later, 18-year old Eric Schubert, contacted the police to assist track down 

the criminal using techniques he learned through his passion of genealogy research.

The murderer was revealed as James Paul Forte, the victim's distant cousin.

The Pennsylvania State Police hailed Schubert for solving a 57-year-old cold case.
