Cisneros had whipped out two knives from a red Target bag and stabbed the first victim, Tak Kam, a 68-year-old dad from Rhode Island, in the abdomen as he exited the subway on West 41st Street and was waiting to cross the street, police said.

She then continued up to 42nd Street and seconds later fatally stabbed Piacenti - a vice president at Bank of America who had just returned from maternity leave.

The slain new mom from Chester, NJ, had posted a touching photo just four days before her murder of herself smiling broadly while holding her infant and standing with her husband. She wrote in the caption how happy she was.

The baby had recently been baptized and Piacenti and her husband, whom she just celebrated her second wedding anniversary with, had been taking her time off to travel.
