Local residents asked to search property for missing Kansas student Aisha Khan

(CBS/KCTV) OVERLAND PARK, Kan. - Local residents are being asked to search their property for signs of missing Kansas student Aisha Khan. She was last heard from Friday when she left a frantic voicemail for her sister saying that she was running away from a man on the University of Kansas-Edwards campus.

Khan's family has offered a $10,000 reward for information leading to her whereabouts. Also, the FBI, local volunteers and Gregg and Missy Smith - whose daughter Kelsey was snatched from an Overland Park Target parking lot four years ago and later found murdered - are all helping in the search effort, according to the Kansas City Star.

Meanwhile, Marla Hansen of Missing Missouri, Inc., told CBS affiliate KCTV that she suggests residents in the metro area search their property because Khan was wearing jewelry that someone may recognize.

"Take a look at your back yard. If there is property that you can't see, go back and walk through it - creek beds, old sheds," she said. "Any of those things could have been dropped."

Khan was last heard from Friday when she left a message for her sister saying that she was running away from a drunk man who was apparently harassing her.

Overland Park Police Chief John Douglass said that on the voicemail message Khan left, "You hear her say he may have tried to kiss her or something like that, and she hit him and ran away," reported the Kansas City Star.

When Khan's sister arrived to pick her up, she found Aisha's bookbag and cell phone abandoned.

There were no security cameras in the area of the University of Kansas-Edwards campus where Khan was last seen, but a spokesperson told KCTV that the university has plans to add cameras in the future.
