The search for a Northern Illinois University female student continued Tuesday as police ask the public for help.
Antinette J. Keller, 18, -- known as Toni by family and friends -- was last seen around noon last Thursday after she told friends she was going for a walk near West Lincoln Highway, which is not far from NIU's campus.
Tuesday's search, which included a K-9 unit, was focused on an area near Annie Glidden Road and Lincoln Highway in DeKalb.
Keller's father, Roger Keller, is aiding in the search. Her mother, however, is in the hospital being treated for anxiety resulting from her daughter's disappearance .
At a press event at NIU, officials from the office of student affairs provided ideas on how students can help in the search, but advised them not to go out on their own. They said the wooded area near campus is too dangerous for students to search and primarily asked students to pass out fliers.
Toni Keller is white, stands 5 feet, 6 inches tall and weighs approximately 130 pounds.
She has brown hair and blue eyes, and was last seen wearing blue jeans, gray jacket, and a scarf. She has a small piercing in her right nostril and a tattoo of three sunflowers on the upper portion of her chest.
She is an art student and may have been carrying a portfolio and professional camera.
Anyone who might have seen Keller or might have information on her whereabouts is asked to call NIU Police at 815-753-1212.
