Medical examiners were performing tests to determine an exact time of death.

Detectives have combed through pictures and documents trying to find a relative to notify. They found a photo of the twins as young girls sitting on Bing Crosby’s lap and another of the pair in tap shoes.

Investigators learned that the sisters appeared regularly on the weekly television musical show “The Hoffman Hayride” in the 1950s and that they entertained troops at several military bases.
