Ortega had been working for the family for almost two years when she brought the two siblings to the back bathroom of their Upper West Side apartment and stabbed them to death.
Ahead of hearing her fate, a tearful Ortega, 55, apologized in court to Lucia and Leo's family. The children were later found in the bathtub when their mother returned home to the bloody apartment. Their father was out of town.
Karen Rosenbaum, a psychiatrist brought forward by the defense, testified that Ortega said devil "voices told her to kill people, kill herself and eventually she told me they told her to kill the children".
On the day of the murders, Krim was on a plane returning from a business trip to the West Coast while Marina was out with Nessie, the couple's second child, who was then 3 years old.
Ortega said she wasn't feeling well but wasn't able to go to the doctor.
"The defendant's son, Jesus Frias, sat in front of a traumatized jury, winking and grinning at the jury members as if it were some kind of reality TV show he wants to win", the mom said. Kim said that during the investigation, neither the babysitter nor her family showed no regret over the death of children. They said she had complained of seeing shadows that followed her, cried frequently and talked about a "black man" who was trying to split up her family. "Unfair to us, unfair to the world".

Prices are up to the highest levels they've been in three years, but still far below 2008's all-time high of $4.11. Grand Rapids is also seeing an increase of 8 cents per gallon, with a new average of $2.81/gallon.
"I ask for a good deal of goodness".
She said she was asking forgiveness from God and the children's parents, adding she had not been feeling well on the day of the murders.
The children's parents, Kevin Krim, 42, and Marina Krim, issued statements thanking the judge and jurors and the district attorney's office.
Judge Carro was not moved. Ortega, a USA citizen originally from the Dominican Republic, had stabbed Lulu 30 times.
Kevin also testified in heartbreaking detail about learning that two of his children were dead and seeing their bodies at the hospital.
During the seven-week trial, jurors grappled with whether Ortega had been too mentally ill to understand what she was doing when she killed the children. Ortega, who's from the Dominican Republic, had been recommended by her sister, a nanny for another NY family, and her background and references were faked by her family.
