because they were purple. >> the next day, investigators got a potential lead. >> police got a call from a man who had been kind of scrounging around behind another convenience store when he came upon a purple pair of shoes. >> the purple shoes are almost certainly julie's. the laces were missing. a bowling bag and some receipts with julie's name left no doubt the items were hers. the site was just a half mile from the convenience store where julie has last seen alive. >> we found evidence that things were taken out of the trunk of her car. and she was probably forced into the trunk, then she was driven five or six miles away from there, where her body was found. >> normally, the evidentiary value of the items would be significant, but not this time. >> the civilian that had found those items had at first taken them home.
