Kevin Krim CNBC: Father Returns From Business Trip After Two Children Murdered By Nanny

More details are being released on the murder of two New York children by their nanny.

On Oct. 25, Marina Krim returned to her Manhattan apartment to find two of her three children dead in the bathtub at the hands of her 50-year-old nanny, Yoselyn Ortega.

Krim's 2-year-old son Leo and 6-year-old daughter Lulu were found with multiple stab wounds in the bath along with Ortega nearby who failed to kill herself by slitting her own throat.

Marina arrived at the Upper West Side home with her three-year-old daughter Nessie who was with her at the time of the attack, according to the New York Post. The mom of three returned to her home after Ortega and the two children were missing from meeting Marina and Nessie at a nearby pool.

A neighbor reported to the police that she believes she was the last person to see the children alive.

 "I was playing with the children in the elevator," said apartment resident Charlotte Friedman. "The girl looked so delightful. I asked her if she was going on a play date or something and she said she was going home. She was smiling, happy, happy happy. The nanny just smiled - and nothing. The nanny was a colder type from most nannies that I have encountered. She was poker faced. She wasn't the warmest person. I never saw her as the warmest nanny."

The nanny was brought to New York-Cornell Hospital and police said as of Friday morning that she remains in a stable condition after slitting her throat and wrists.

Marina works as a pediatrician and her husband Kevin is the senior vice president and general manager of CNBC Digital. Mr. Krim is a Harvard graduate that has recently worked at Bloomberg and Yahoo!, according to the Daily Mail. The family moved from San Francisco to New York when Mr. Krim started his job with CNBC in March.

Mr. Krim was on a business trip at the time of the incident and was met by police upon his return. He was escorted from the airport by police and remains at his wife's side at St. Luke's hospital where his children were taken.

Police say that Mrs. Krim has been unable to talk due to the shock of the horrible event.

Ortega, originally from the Dominican Republic, was not a live-in nanny and had no criminal record.

According to Kevin's mother, Karen, the family hired the nanny from the Dominican Republic a year ago.

"Kevin told me that she was a nice girl," the grandmother told the New York Post. "How could she do something like that? The children were angels."
