Did they possibly search Ricardo's computer at that date and get more info?
KC told Iassen that she and Ricardo broke up right around her birthday - which is March 17th or 19th?, St. Patrick's Day I think, (maybe that's why all the shamrocks.) Maybe she got depressed and wanted to be out on her own after Ricardo broke up with her. She was already talking about getting an apartment for just herself and caylee back then. On June 27th she tells Iassen she likes "this kid" (Tony), "an extreme amount." And then she tells Iassen after he asks, that she's known Tony for a year!
On July 13th (when it sounds like she's lining up Iassen to be her next guy already "just in case") she tells him, "I'm pretty hung up on Tony, and realistically, if he moves back to new york next year, my relationship will end. sucks to know that inevitably, unless I were to drop everything, i'm going to lose someone close to me."
Does "unless I were to drop everything" = kiling caylee?
