Two elderly sisters were found dead inside their Queens apartment Wednesday, police said.

The victims were found on the floor unconscious and unresponsive inside their apartment building along 108th Street.

The sisters, Leah Roth, 88, and Ilene Roth, 79, were discovered by a building super, who entered the apartment after getting complaints of a leak.

Investigators are trying to figure out how the sisters died – but at this point, there are no signs of trauma or forced entry.
