Dru was last seen late Saturday Nov. 22nd, as she was leaving the Columbia Mall in Grand Forks where she worked. Her mother, Linda Walker, said her daughter was talking to her boyfriend in Minneapolis on her cell phone about 5 p.m. Saturday when he heard her say, "Oh, my God," before the phone went dead.
The boyfriend called Sjodin's roommate to ask about her after a second call about three hours later that lasted only about a minute, with no conversation. The roommate called police after Sjodin did not show up for her 9 p.m. shift as a waitress in a Grand Forks bar.
Police traced the second call from Sjodin's cell phone to the area near Fisher. Police said the cell phone signal put it within about five miles of the tower near Fisher from about 8 p.m. Saturday until the signal faded out 24 hours later.
Police said Sjodin's red car was found in a Columbia Mall parking lot with a package inside that she apparently had bought at the mall. They found no sign of a struggle
