One eagle-eyed reader noticed something in the phone records that has yet to be reported: On the day of Maura's disappearance, Bill was trying all day to speak to Maura. But they never connected. There was only one time when Maura called Bill from her cell phone that day. And it happened at the same time Bill was calling Kate Markopoulos. The call went to voice mail and Maura never called him back after that.
Or was Maura standing beside Kate when the call came in?
