NEW YORK (CBSNewYork) — A 71-year-old woman is dead and her 87-year-old husband is critically injured after being stabbed inside their Brooklyn home.

Police were called shortly before 7 p.m. Saturday to a house on Garden Street in Bushwick.

Officers found Maria Rodriguez with multiple stab wounds to her torso. Her much older husband was stabbed in his chest and slashed in the arms.

Rodriguez was pronounced dead at the scene, and the husband was rushed to Bellevue Hospital.

Sources told CBS2 a home care aide was unable to get into the home and called the couple’s relatives, who climbed in through a window and made the grisly discovery.

“Early morning, they … I just heard pounding the door. I think it was the nurse pounding the door,” a neighbor said. “I just talked to her yesterday. The day before, she asked me, ‘How’s everything?’ I said, ‘OK, yeah.'”

It’s unclear what led up to the deadly stabbing, and so far no arrests have been made, but police believe the couple’s attacker knew them.
