A New York City couple who lost two of their children in an attack police blamed on their nanny has welcomed a baby boy.

Kevin and Marina Krim announced the news Friday on the Facebook page for the Leo and Lulu Fund.

The Krims say Felix Harrison was born weighing 8 pounds, 10 ounces. Everyone is healthy and happy.

The fund was created in memory of their 6-year-old daughter, Lulu, and 2-year-old son, Leo, who were found dead in their apartment Oct. 25, 2012. Their 4-year-old daughter, Nessie, wasn't home at the time.

The fund raises money for children's education. The family has also posted numerous memories of their children and described their grief there.

The nanny, Yoselyn Ortega, has pleaded not guilty to murder charges.
