(NEW YORK) -- The New York City mother who came home to find her two young children allegedly stabbed to death by a trusted nanny, then watched helplessly as the woman knifed herself in the throat and slit her wrists, police said Friday.
At a press conference Friday, Police Commissioner Ray Kelly said nanny Yoselyn Ortega, 50, remains on a breathing tube after being rushed to a hospital Thursday evening, and has yet to be interviewed by cops or formally charged.
Kelly, and neighbors who knew the woman for years, said Ortega had no known history of mental illness.
The nanny, a naturalized U.S. citizen who was born in the Dominican Republic, worked for the Krim family for two years and had been referred to them by another family, the police commissioner said.
Ortega lives with her son and her sister. They are cooperating with police, Kelly said.
Outside the luxury building where the victims' lived, neighbors have created a makeshift memorial, laying flowers and leaving condolence messages for the distraught mother, Marina Krim and her husband Kevin Krim.
Marina Krim came home Thursday evening around 5:30 p.m., after taking her 3-year-old to a swim class at the YMCA. She arrived home to a dark and quiet apartment and initially thought the nanny had taken the children out. Upon entering a bathroom, Marina discovered Ortega and her two other children Lucia, 6, and 2-year-old Leo dead in a bathtub filled with blood, authorities said.
It was at that moment that Ortega is believed to have slashed herself, Kelly said.
Ortega is in critical but stable condition and has no criminal record, police said.
A preliminary police investigation had not yet yielded a possible motive for the deaths.
The children's father, a CNBC executive, was on a business trip in San Francisco at the time of the murders. He flew home Thursday night and police picked him up at the airport and rushed him to his family, authorities said.
