A 72-year-old man jumped to his death late Sunday night from his Manhattan apartment, where cops later found his 78-year-old wife — dead on a living room sofa with multiple stab wounds, according to police.

The couple’s bodies were found at 210 Sherman Avenue in Inwood. Their identities were being withheld pending family notification.

Authorities said they were responding to a 911 call when officers found the male in front of his building — sprawled out on the pavement — around 10:20 p.m.

He was unconscious when cops arrived and wound up being pronounced dead at the scene. His wife was later discovered inside the residence — with several stab wounds to her torso.

Police said they recovered a knife at the scene and that an investigation remains ongoing.
