Mother returns home to find her toddlers stabbed to death in UWS apartment

57 W. 75th St.

An Upper West Side nanny stabbed to death two small children who she was taking care of while their mother was out, then slit her own wrists in a failed suicide bid this afternoon, sources said.

The children’s 36-year-old mother came home from running errands at about 5:34 p.m. when she walked into the nanny — Yoselyn Ortega, 50 — in a pool of blood in the kitchen, sources told The Post.

She rushed to the West 75th Street apartment’s bathroom, where she found her two youngest children, ages 2 and 6, with several stab wounds in their small bodies.

“Something happened to my kids!” the sobbing mother screamed, according to a witness.

The kids appeared to still be breathing when they were rushed to St. Luke’s-Roosevelt Hospital Center, but they were pronounced dead on arrival.

The mother — who was out with her oldest child — was also taken to St. Luke’s-Roosevelt, where she had to be sedated, a source said.

Ortega, who was is in police custody, was taken New York Presbyterian Hospital in critical but stable condition.

The children’s father was on a plane from San Francisco and had not been told about his children’s death, a source said.

A neighbor told The Post she heard “the mother screaming hysterically” when she arrived at the apartment.

“It’s horrifying, it’s a very quiet building,” said the neighbor, who met the nanny for the first time yesterday and described her as “very quiet.”

“She just stared ahead,” the neighbor added.

“Its horrifying, its a very quiet building. They are a beautiful, quiet family.”

Cops are yet to confirm the victims’ identities and ages.
