New York ( CNN ) -- Every parent 's worst nightmare became reality for a New York City couple when their 6-year-old daughter and 2-year-old son were stabbed to death , allegedly at the hands of their nanny . Two months after that October tragedy , Marina and Kevin Krim have embarked on a cross-country trip , adding a literal dimension to their road to recovery by sharing images and insights gleaned from their journey on Facebook . With the new year , the couple and their 4-year-old daughter , Nessie , set out from Los Angeles `` hopeful that 2013 will be a year of healing , growth and peace . '' `` She saves us every day , '' Kevin Krim wrote on Facebook , referring to his surviving daughter . The pair have created the Lulu & Leo Fund in their slain children 's names to carry on their `` love of arts and sciences education . '' It 's not clear how much money the couple has raised , but its purpose is to support `` art and science education for young children in schools , museums , and other community institutions , '' according to a statement . As the couple head east aboard a recreational vehicle , the Krims said they hope `` to experience some inspiring moments that will help us with our healing and rebuilding when we get back to NYC . '' Included in that post was a `` gorgeous sunset at the beach that Lulu and Leo painted for us . '' They said they also drew comfort from inspirational images as they reached Sante Fe , New Mexico , on Saturday . A mother 's greatest fear . `` We strolled through a few art galleries today and found some pieces at the Canyon Road Contemporary Art Gallery that we are sure Lulu and Leo would have loved , '' the couple wrote . In November , a New York grand jury indicted Yoselyn Ortega on first- and second-degree murder charges in the deaths of Lucia and Leo Krim . Their mother returned home to her Upper West Side apartment , police said , and found her children in the bathroom . She also saw the nanny stab herself with a kitchen knife , authorities said . Ortega is currently being held at the Elmhurst Hospital Prison Ward , according to the New York City Department of Correction . Since their children 's death , the couple have sought to use art from their trip in the healing process , posting the images online . `` We created the Lulu & Leo Fund to help more children benefit from these education experiences in art and science , '' the couple say in the fund 's mission statement , describing how much Lulu cherished her `` beloved 'Art Afternoons ' class at the Metropolitan Museum of Art . '' The page has since accumulated more than 14,000 `` likes '' on Facebook .
