The New York City parents whose nanny allegedly murdered two of their children in October are having another baby, they announced Thursday on Facebook. “We are filled with many emotions as we look to the future, but the most important one is hope,” Marina and Kevin Krim wrote on the Facebook page set up in memory of their children. Lulu and Leo Krim, 6 and 2, respectively, were allegedly stabbed to death by their nanny, Yoselyn Ortega, in October while Marina Krim was out with couple’s other daughter, Nessie. Ortega, who also allegedly stabbed herself in the throat, has been charged with their murders.
