the prosecution said the investigator told the jury he used cell phone data to being trat moores' movements. in the days before the disappearance they showed up near heather's workplace. some of the bars she liked, even her home. the prosecution suggested that the couple was stalking her and then in the early hours of december 18th, 2013, with heather's roommate out of town, the prosecutor said the couple struck. it began here. the prosecutor showed the jury surveillance video of sidney watching into a walmart and purchasing a pregnancy test for heather. >> as soon as they leave from walmart they go and call her. why? >> the prosecution's theory was that sidney had called heather to come and get the taste, take it and meet up with him later at the landing. they said what she didn't know is that team would be there, too. >> there's no doubt that sidney is the bait in this hunting.
