Child Is Coming for City Couple Who Lost Two in Nanny Case

Facebook Marina and Kevin Krim posted to Facebook on Thursday that Ms. Krim is expecting a son in the fall. The Facebook page contains an image from a mural that the Krims say is appropriate to the occasion.

Just over six and a half months after two of their children were found fatally stabbed in their Upper West Side apartment, Kevin and Marina Krim announced to the world this week that Ms. Krim is pregnant.

“We are very happy to let you know that Marina is expecting a baby in the fall,” the couple wrote on Facebook on Thursday. “Nessie can't wait to welcome her new baby brother. We are filled with many emotions as we look to the future, but the most important one is hope.”

Nessie Krim, who is 4, is the Krims' only surviving child. On Oct. 25, the police have said, Ms. Krim returned home to West 75th Street with Nessie from a swimming lesson to find her 6-year-old daughter, Lucia, and her 2-year-old son, Leo, dying from knife wounds, and the children's nanny, Yoselyn Ortega, stabbing herself in the throat.

Ms. Ortega was charged with the children's murders. Last month, she was found mentally fit to stand trial.

The Krims - she is 37, and he is 38 - announced Ms. Krim's pregnancy on the Facebook page of the charity they have started in their slain children's memory, the Lulu & Leo Fund, which provides arts and science classes to underprivileged children.

The Facebook posting had received more than 5,000 “likes” and nearly 1,000 comments by Friday morning.

“This is the happiest magical news we all could hope for,” one woman wrote, adding: “This little boy is a symbol of so many things. Your hearts were broken, but you never let your spirit dwindle.”
