New York ( CNN ) -- The parents of two children allegedly slain by their nanny in New York City last year are expecting a child this fall , roughly a year after the nightmare deaths , according to a Facebook post . `` We are very happy to let you know that Marina is expecting a baby in the fall , '' parents Marina and Kevin Krim said Thursday on the `` Lulu & Leo Fund '' memorial page , established for their late daughter Lucia `` Lulu '' Krim , 6 , and her brother Leo , 2 . Police say on that October 25 , 2012 , the children 's mother returned to the family 's Upper West Side apartment , found Lucia and Leo dead in the bathroom and saw the nanny stab herself with a kitchen knife . Krim left two of her children with the nanny , Yoselyn Ortega , 50 , to take her 3-year-old child , Nessie , to a swim lesson at a nearby YMCA , New York Police Commissioner Ray Kelly said . She had expected to meet the nanny around 5:30 p.m. at a dance class , but when Ortega failed to appear , the mother went back to the apartment . Ortega was arrested in November and later indicted on first- and second-degree murder charges , court documents show . Ortega has pleaded not guilty and has been ruled emotionally fit to stand trial , according to prosecutors . The children 's grandmother , Karen Krim , told CNN on Friday : `` We are thrilled . '' `` Nessie ca n't wait to welcome her new baby brother , '' the children 's parents say on their Facebook post . `` We are filled with many emotions as we look to the future , but the most important one is hope . '' Kevin Krim is a senior vice president for CNBC Digital and a former Yahoo executive . Ortega , a native of the Dominican Republic , has been a naturalized U.S. citizen for 10 years . Friends introduced the family to Ortega , and she had worked for them since Leo 's birth , police said . Ortega was not a live-in nanny , but Marina Krim 's blog , `` Life with the Little Krim Kids , '' offered the loving mother 's view of a family life that included Ortega as a member . In February 2012 , the Krims traveled to the Dominican Republic , where they met Ortega 's family . `` We spent the past nine days in the Dominican Republic , '' Marina Krim wrote on February 18 . `` We spent half the time at our nanny , Josie 's sister 's home in Santiago and the rest at Balcones de Atlantico in Las Terrenas , a condo-style hotel where the 'Real Housewives of Dominican Republic ' and their families hang on weekends . It was wonderful . '' She added , `` We met Josie 's amazing familia ! ! ! And the Dominican Republic is a wonderful country ! ! '' One photograph showed the families together , Ortega holding the girl who was learning how to swim at the time her siblings were killed .
Marina and Marina Krim 's say child is expected about a year , about a year after children 's deaths . Mother found the children dead and saw the nanny stab herself in about a year , police say . The nanny has been indicted on first- and second -degree murder charges . Parents : `` We are filled with many emotions ... but the most important one is hope ''
