snipped from article (still haven't found the correct docs because I do remember reading the text exchange between the 2)
"On July 15, Cindy reported Caylee missing and send this text Call me ASAP, Major prob. To Casey.
July 16, Caseys boyfriend , Anthony Lazzaro wrote her a message where is Caylee?
Eight minutes afterward, he send another message Why wouldnt you tell me, of all people? I was your boyfriend that cares about you and your daughter. It doesnt make sense to me. Why would you lie to me, thinking she was fine and with your nanny?
Six minutes afterward, he send another text Who is this Zannie nanny person?
They do have Casey text message Caylee is missing. She has been for 32 days now. Please, if you have any information, call me on my cell at home.
