From the article you link:
Dru Sjodin, 22, of Pequot Lakes, Minn., was last seen late Saturday afternoon, as she was leaving a lingerie store in the Columbia Mall in Grand Forks where she worked.
From the article at post #54:
Sjodin left work at Victoria's Secret in Columbia Mall at 4 p.m. Saturday; she spent nearly an hour shopping in the mall, finishing in Marshall Fields about 5 p.m., Hedlund said. While in that store, Sjodin began a 10-minute cell-phone conversation with her boyfriend, who lives in the Twin Cities area.
I'll bet she was last in Marshall Fields and not Victoria's Secret, and maybe in the scheme of things it doesn't matter, except if they're hoping to get people shopping at those stores at that time to wrack their brains if they saw anything that might aid in the search, the misinformation could be less than helpful.
This whole thing hits kind of close to home. I live in the Twin Cities but my wife and I were in the Grand Forks Colombia Mall 3 weeks ago. She even dragged me though the Victoria Secret. Our family's cabin is about 4 miles outside of Pequot Lakes.
It's just kind of freaky to think I probably passed by this girl not too long ago.
