The Manhattan nanny accused of brutally killing two children in their Upper West Side home was indicted on murder charges Wednesday.

The charges are in court records released Tuesday, The New York Times reported. 

Six-year-old Lucia Krim and her 2-year-old brother, Leo, were killed Oct. 25. They were found by their mother when she came home with the victims' 3-year-old sister.

The 50-year-old nanny, Yoselyn Ortega, remains hospitalized with self-inflicted stab wounds, and police have said they don't know if Ortega has a lawyer.

She's expected to be arraigned via video. The hearing has not yet been scheduled.

Police say Ortega, who is a Dominican immigrant and a naturalized U.S. citizen, stabbed the two children in her care before trying to kill herself.

She had recovered enough from her wounds by Saturday to be interviewed by police in her hospital bed at New York Presbyterian Weill Cornell Medical Center. After the interview, she was formally charged with two counts each of first- and second-degree murder.

The couple's apartment building sits in one of the city's most idyllic neighborhoods, a block from Central Park, near the Museum of Natural History and blocks from Lincoln Center for the Performing Arts. The neighborhood is home to many affluent families, and seeing children accompanied by nannies is an everyday part of life there.

Some of Ortega's friends and relatives said she appeared to be struggling emotionally and financially recently, but they still couldn't believe she could have committed such a heinous act.
