Two senior women.

Two brutal murders.

Two homes deliberately set on fire. In 2010, the body of Dolores Alliotts was discovered after a fire in Palisades Park, New Jersey.

Just months later, Joan Davis was found dead following another house fire in nearby Teaneck.

Investigators quickly faced a chilling question: were these murders connected?

Now, more than a decade later, the Bergen County cold case remains unsolved.

Authorities have examined possible links between the victims, explored an FBI profile of a suspect, and revisited the case as new video evidence became public 10 years later.

Could one person be responsible for both killings - and what will it take to finally bring justice?
