Yoselyn Ortega, the Dominican Republic nanny for the Krim family, has been indicted for murder of Marina and Kevin Krim's 2-year-old son Leo and 6-year-old daughter Lucia.
A grand jury in New York indicted the 50-year-old nanny for the charges of first and second degree murder of the two children, according to CNN.
Ortega is recovering from attempted suicide at Weill Cornell Medical Center and remains under police guard.
During questioning, Ortega told police that she was angered the Krim family wanted her to do housework.
The Daily Mail reported the New York City police official's comments on Ortega's questioning saying, "She said something like, 'I'm paid to watch the children, not clean up and do housework.'"
A date has yet to be scheduled by the Manhattan District Attorney for the nanny's arraignment.
Ortega had financial troubles that led to the Krim's offering extra money in exchange to do housework. The nanny did not take the offer kindly as the family planned on giving Ortega an additional five hours a week of work which got in the way of her medical appointments.
On Oct. 25, Marina Krim returned to her Upper West Side apartment in New York in the evening to find both of her children dead in the bathtub at the hands of her nanny bleeding nearby.
Police say they Ortega started cutting herself when Krim returned home.
"We believe now that the nanny began to stab herself as the woman entered the room," said Police Commissioner Ray Kelly shortly after Ortega was first put in police custody. "We initially thought that had already been done but now information is coming out that she did it as the mother entered the bathroom."
Marina arrived at her Manhattan 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.
Mr. Krim's mother, Karen, commented recently, "It was just a horror story."
"I was their grandmother. It is really horrible," said Karen, who was interviewed on Wednesday at her Calif. home.
Kevin Krim is a CNBC executive and was returning from a business trip in San Francisco at the time of the killings.
