Police say the 74-year-old woman who was discovered dead in her Harlem apartment on Thursday may have been the victim of a robbery.

Investigators were questioning Juana Garcia’s son who allegedly found her inside the apartment on East 105th Street face down on her bed with a cut on her head, cops said.

Authorities say she was pronounced dead at the scene.

Her son, whose identity wasn’t immediately released, told cops cash was missing from a closet in a bedroom, sources said.

He has not been charged with a crime and no arrests have been made.
