Horror for nanny jury

The Manhattan jurors already sickened by grisly photos of two children slain by their nanny endured another ordeal on Monday when a city medical examiner testified on how the 2-year-old boy and 6-year-old girl were butchered.

One woman on the panel was left shaking after hearing Dr. Susan Ely describe the manner in which Yoselyn Ortega cut toddler Leo Krim’s neck with a kitchen knife in his family’s Upper West Side apartment in 2012. Another juror’s mouth fell open for minutes after she heard about Lucia Krim’s abdominal wounds.

One thing was clear, the coroner told jurors: The children suffered horribly before they died.

Lucia likely twisted her body to get away, the doctor testified. Leo suffered six wounds, all to his neck, she said, and had no blood left in his body when he arrived on the autopsy table.

“They didn’t die initially,” Ely said. “Bleeding to death takes minutes.”

Ortega, 55, showed no emotion as she listened to her actions recounted. The once-trusted nanny, who claims her body was overtaken by the devil, is mounting an insanity defense.
