Anonymous Facebook group claims 'killer' nanny is innocent

A Facebook group claims that accused killer nanny Yoselyn Ortega is completely innocent – and that cops arrested the wrong woman.

The page called Support Innocence of Nanny Yoselyn Ortega popped up on Oct. 29 and claims that the Upper West Side Nanny did not brutally stab two kids under her care.

Nineteen anonymous Facebook users have “liked” the page – but dozens have blasted its creators.

"You should be ashamed of yourself for putting this on Facebook!” wrote Anne Sullivan Tillman. “Hasn't the family been through enough? Two beautiful children were killed by this monster! Shame, shame on you!

One sick post even speculates that the children's grieving mother, Marina Krim, killed the kids and stabbed Ortega, because the nanny was having an affair with their father, Kevin.

"... They probably had an encounter here in New York at some point. Kevin maybe decided to break it off and scorned her," the insane post muses. "Could there be a possibility that Marina found out about this affair and decided to get even with husband and killed her kids and in the process of Yoselyn trying to defend them she stabbed her in her neck then claimed otherwise?"

Facebook users blasted the claims.

"So the blame is being shifted from the nanny/murderer to the victim/mother who lost 2 of her children to a woman who clearly lost her mind?" wrote Mishy Park. "Gimme a freakin break!!!!!!!!!!!!!"

Ortega was arrested and charged on Saturday with the horrific slayings of Lucia and Leo Krim, ages 6 and 2.

Marina came home to find the bloodied children dying in the tub as Ortega stabbed herself in the neck, cops said.
