A couple whose two young children were allegedly murdered by their nanny have revealed they are expecting a baby boy.
The deaths of six-year-old Lucia and two-year-old Leo Krim sent shockwaves across America last October.
Their mum Marina was with their little sister, Nessie, at swimming lessons when their nanny allegedly stabbed the two children to death in their Manhattan apartment.
But yesterday, Marina and husband Kevin posted the fantastic news on a Facebook page dedicated to their late children that they are to be a mum and dad again.
They wrote: "We are very happy to let you know that Marina is expecting a baby in the fall.
"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."
They signed off that the family was 'very grateful to you all for your amazing support'.
The Krims left Manhattan shortly after the tragedy and stayed with family in California for several weeks. They started a slow return via a cross-country road trip, and posted frequent updates on their Facebook page.
Meanwhile, their nanny, Yoselyn Ortega, has been charged with killing Lucia and Leo. She was found fit to stand trial on April 5. Her lawyer is challenging those results, arguing Ortega is not mentally stable.
The 50-year-old, who tried to slit her own throat as Marina came home and found her two children lying in a pool of blood, has pleaded not guilty to the murders.
Recently, Marina wrote a tribute to her children that was read out at a charity event .
"Five months ago, on an ordinary October day in New York City, I lost two of my best friends, my 6-year-old daughter Lulu and my 2-year-old son Leo," she wrote.
"Nessie our middle child, just 3 years old at the time, became an only child. My entire existence was shattered.
"My simple charming old life, from the moment I woke up till the moment I went to sleep, revolved around my kids and I was extremely proud of that.
"My most magical moments with Lulu and Leo almost never involved material items. It was the look of pride I would see on Lulu's face when I would pick her up from art class. It was watching Leo's deep brown curious eyes track a caterpillar in the grass.
"My most important challenge is to remember and see the magic in the present every day."
The Krims have established a fund in memory of their children to promote science and art education.
