 A neighbor of the family who shared an elevator with the nanny and the kids 30 minutes before they were found dead said nothing seemed amiss.“The kids looked normal. The nanny looked normal,” said neighbor Charlotte Friedman. “She had a poker face. There was no indication that something like this was going to happen.”Little Lucia appeared full of joy and told Friedman she had just gone dancing.Friedman, who lives on the seventh floor, said she typically ran into the nanny a couple of times a week and always greeted her with a smile — but Ortega never reciprocated.“She wasn’t warm,” Friedman said. “Usually when you smile at a nanny and the kids, the nanny smiles back. It’s instinctive. But she had a poker face. I didn’t get the sense she was evil, just cold.”Ortega’s neighbors in Hamilton Heights said the deeply religious woman ran a side business selling makeup and sometimes complained about being broke.“She had said that someone owed her 100 or 200 dollars for makeup she sold,” said Maria Lajara. “She said, ‘Someone owes me money. Pray for me.’”Lajara said Ortega, 50, adored the Krim children.“She was very happy with the work,” Lajara said.“She liked the kids. She would show pictures of them. She was happy with her boss and never had any problems. She must have lost her mind.”Another neighbor said Ortega begged her for work about two years ago.“She said, ‘I’ll clean. I’ll do anything,’ ” the neighbor recalled.Karen Krim said her son and his wife lived for their kids.“Our poor son. He was such a wonderful father,” the grandmother said. “The thing I’m most proud of him for is he was such a fabulous father.”Karen Krim said that the family hired Ortega two or three years ago. Whenever they left town with the children, the Krims would buy Ortega a flight back to the Dominican Republic.The News on Friday obtained a photograph of Ortega, showing her clutching little Lucia and her sister Nessie while the Krims were on a family trip to the Dominican Republic in February. They stayed part of the time with Ortega’s relatives. The girls, smiling wide, were captured in matching embroidered tan outfits and holding pink flowers.The slayings rattled the leafy, well-heeled neighborhood, which teems with stroller-pushing nannies. Scores of well-wishers, many of whom didn’t even know the Krims, dropped off flowers outside their building.“Dear Krim Family,” read a note wedged into the mountain of bouquets. “We weep with you at your horrible loss. There are no words that can express our sadness. We pray for you and your beautiful children.”rschapiro@nydailynews.com ||||| The deranged nanny who allegedly butchered two adorable young children entrusted to her care was unraveling in recent months — suffering from mental, physical and financial issues, neighbors and police sources said yesterday. 
 
 Yoselyn Ortega, 50, appeared sick and gaunt, her Hamilton Heights neighbors said, and she appeared “nervous.” 
 
 “She lost a lot of weight. She looked very unhealthy. It looked like she was going through some problems,” said Ruben Diaz, 49. “She had aged a lot — like seven years in a few months.” 
 
 She also told people she was seeing a psychiatrist, cops said. 
 
 NEIGHBORS SHARE IN THE HORROR 
 
 NANNY ACCUSED OF STABBING TODDLERS TO DEATH 
 
 PHOTOS: REMEMBERING LEO AND LUCIA KRIM 
 
 “She snapped,” said Celia Ortega, the nanny’s sister. “We don’t understand what happened to her mind.” 
 
 Still, neighbors were shocked that she was suspected of stabbing to death little Lucia Krim, 6, and her baby brother Leo, 2, on Thursday before slashing her own wrists and throat in the kids’ West 75th Street apartment. 
 
 NYPD detectives were unable to interrogate her yesterday, as she remained in a medically induced coma at New York Hospital.

 Law-enforcement sources said Ortega, a Dominican who has been a US citizen for 10 years, complained of money troubles, and her employers, Marina and Kevin Krim, had given her more hours of work. 
 
 They even hooked her up with a family they knew for a baby-sitting job on the side — but the family turned her down after an interview because she was, “a little too grumpy,” a law-enforcement source said. 
 
 But nobody could predict the horror she would allegedly inflict. 
 
 Marina Krim, 36, had taken daughter Nessie, 3, to a swimming lesson but returned to her tony prewar building shortly after 5:30 p.m. because the nanny never showed up with the two other children to meet them for Lucia’s dance class, a source said. 
 
 “She got a call from the nanny saying she’d picked them up from school and she was taking them straight home,” said an employee at the Upper West Side swim and dance facility. “She [Marina] didn’t seem nervous at all; she waved to me.” 
 
 A neighbor who likely was the last to see the children alive said Lucia seemed happy in the elevator only 30 minutes before the unspeakable crime. 
 
 “She [Lucia] looked so delightful,” said upstairs neighbor Charlotte Friedman. “I said, ‘What did you do?’ and she said, ‘Dancing.’ And that was it.” 
 
 Friedman described the girl as “happy, happy, happy.” 
 
 That all changed inside the apartment. Ortega used two kitchen knives in her alleged attack on the helpless children, sources said. Lucia suffered defensive wounds from bravely trying to fight her off. 
 
 She was stabbed multiple times in the stomach and neck, and Leo was stabbed twice in the neck, the sources said. 
 
 “They both suffered. They bled out,” said a source. “The little girl tried to protect herself.” 
 
 When their unsuspecting mom arrived home a short time later, she walked into the bathroom and found her babies lying in the tub fully clothed with stab wounds on their bodies. 
 
 Ortega slashed her own throat right in front of the horrified woman, said Police Commissioner Ray Kelly. 
 
 Marina was later seen in the mezzanine of the La Rochelle building, clutching her surviving middle child, Nessie. 
 
 “She was bent over the child, screaming and holding onto the only live child she still had,” said Friedman. “They were very deep, dark screams. 
 
 “She was screaming things like, ‘I’ll never speak to her again,’ repeating that over and over again. Then screaming things like, ‘It’s all right, you’ll be all right, you’ll be all right,’ ” said neighbor Rima Starr, 63. 
 
 “Then she would get waves of the reality of what just happened and then she’d go into just plain, bloodcurdling screams, with her arms flailing out to the sides. 
 
 “Then, in lucid moments, she’d say, ‘I need a doctor. I need a doctor.’ ” 
 
 Marina was rushed to St. Luke’s Hospital, and when cops arrived, the hysterical woman said, “What are we going to do now? I’ll never go back there again,” law-enforcement sources said. “They can have everything. I don’t want anything.” 
 
 Marina left the hospital and was holed up with Kevin, 37, and relatives at a luxury Manhattan hotel, sources said. 
 
 There was no clear motive yesterday, although Friedman, the neighbor, said Ortega was often aloof. 
 
 “The nanny just smiled — and nothing,” she said of the elevator encounter. “She was a colder type [than] most nannies I have encountered,” Friedman said. 
 
 Ortega’s tearful sister, Celia Ortega, of The Bronx, nannied for a girl in the same ballet class as the Krim girls and recommended her sister for a job with the Krim family. 
 
 Celia said she would tell Marina, “I’d give you my life,” if it would bring back the children. 
 
 Yoselyn Ortega was under guard at the hospital. A toxicology report came back negative for drugs, sources said. 
 
 Yoselyn’s son, a 17-year-old who attends the Bronx Catholic school Mount St. Michael Academy, is staying with another aunt. 
 
 The Krims’ extended family in California was still reeling from the news. 
 
 “Who would do that to innocent children?” said Karen Krim, Kevin’s mother. 
 
 “We’re exhausted,” said William Krim, Kevin’s father. “We’re all devastated here.” 
 
 Students and parents at PS 87 on West 78th Street — where Lucia was a first-grader — were shocked by the news, and all field trips had been canceled. 
 
 “People are very shaken obviously by what happened,” said Beth Servetar, whose son is in the fifth grade. 
 
 “I don’t think anybody really knew what to say to each other. There were watery eyes. The thing we did talk about was how horribly difficult it is to explain to our children what happened.”

 The nanny, Yoselyn Ortega, 50, was interviewed in her hospital bed on Saturday by detectives at NewYork-Presbyterian/Weill Cornell Medical Center, the police have said. 
 
 Ms. Ortega was charged hours later with fatally stabbing the children, Lucia Krim, 6, and Leo Krim, 2, in a bathroom in the family’s apartment last month shortly before their mother, Marina Krim, returned from a swimming lesson with her other young daughter. 
 
 Ms. Ortega waived her right to have a lawyer present during questioning, the official said, although she did not confess to the killings. 
 
 She told the detectives, “Marina knows what happened,” the official, who spoke on the condition of anonymity because he was not authorized to discuss the case, said Sunday.

 The police have said that Ms. Krim walked into the bathroom to find Ms. Ortega stabbing herself in the throat, with the dying children bleeding in the bathtub. 
 
 The official said that Ms. Ortega was not medicated but that she seemed “spacey.” 
 
 The official said that while the Krim family did not have problems with Ms. Ortega and seemed to live an idyllic life, Ms. Ortega, based on what she told the investigators, had a different view.

 “She had resentment towards the parents” and said “they were always telling her what to do,” the official said. 
 
 Ms. Ortega was charged with first-degree murder in the killings. It was not clear when she would be arraigned or whether she had a lawyer. 
 
 The killings of the two young children sent a chill through New York City because they took place in a luxury apartment building a block from Central Park in a neighborhood where nannies are woven into the fabric of family life. In the days afterward, investigators and those closest to Ms. Ortega and the Krim family were at a loss to provide an explanation for the violence.

 That was in part because investigators could not question Ms. Ortega because of the serious nature of her self-inflicted injuries. But also the relationship between Ms. Ortega and the family that had employed her for about two years gave no hint of the kind of discord or anger that would precipitate the violence that the police say Ms. Ortega inflicted on the children who had been in her care. 
 
 Relatives of the Krims said they had treated Ms. Ortega as a member of their own family and would even pay for her to travel to the Dominican Republic so Ms. Ortega could visit her family while the Krims went on vacation. 
 
 And a friend of Ms. Ortega recalled how fondly that she would speak of the Krims, saying she was well paid and treated decently. Ms. Ortega said she happily put in extra hours to help Ms. Krim whenever she needed it. 
 
 Still, Ms. Ortega had had some financial difficulties recently, and she had been forced to move out of an apartment in the Bronx and back in with her sister in Harlem. She had appeared harried and under stress, those who know her said. 
 
 On the day of the killings, the police said, Ms. Ortega was supposed to meet Ms. Krim at a dance studio. She never showed up, so Ms. Krim went back home to see what had happened.
– The 50-year-old nanny accused of fatally stabbing two young siblings in her care had been on a downward spiral in recent months, losing weight, worried about money, and growing increasingly withdrawn, according to accounts by friends and family to the media. But Yoselyn Ortega, who remains in an induced coma after trying to kill herself, seemed to have no problems with the family she worked for. "They treated her like family," the victims' grandmother tells the Daily News: New York Post: “She looked very unhealthy," says one of her neighbors. "It looked like she was going through some problems. She had aged a lot—like seven years in a few months.” New York Times: "She was unraveling," is the story's first sentence. Ortega, a Dominican who has been a US citizen for a decade, shared an apartment with her son, sister, and niece, and her sister told a friend that Ortega felt lately like "she was losing her mind." The family took her to a psychologist. Daily News: Ortega sold cosmetics on the side to try to make extra money. “She had said that someone owed her 100 or 200 dollars for makeup she sold,” says one neighbor. “She said, ‘Someone owes me money. Pray for me.’”
