New York's alleged child-killing nanny was not only tired of being told what to do, she had an "epic argument" with her employer the day before the children died, according to a law enforcement source. Yoselyn Ortega told detectives "that she was involved in an epic argument with Marina Krim," the source tells Radar. And Krim ignored the nanny when she said goodbye at the end of the day, which "made her very, very angry."
Ortega apparently became very animated when recounting this hot-tempered day. She said she also had several arguments with her employer about how to care for the kids, 6-year-old Lucia Krim and 2-year-old Leo. According to the law enforcement source, Krim accused her of neglecting the children at times and "giving them junk food when she was out of sight." (Read more Yoselyn Ortega stories.)
