Father of slain kids testifies at nanny's New York trial

NEW YORK (AP) — The father of two young children allegedly killed by their nanny has described the harrowing moments he learned of their deaths just after his plane landed at New York's Kennedy Airport.

Kevin Krim told jurors in the trial of Yoselyn Ortega (YOH'-sih-lihn ohr-TAY'-guh) on Tuesday that when he switched off the airplane mode on his phone he was flooded with texts from concerned neighbors and friends.

He called it the "worst thing imaginable."

Hours later at the hospital, Krim tearfully described kissing his children goodbye as they lay dead on stainless steel tables.

Ortega has pleaded not guilty in the fatal stabbings of 2-year-old Leo Krim and 6-year-old Lucia Krim in October 2012. Prosecutors say a motive may never be known.
