Authorities in Aurora are getting some help in their search for a missing 6-year-old girl. Two experts from the National Center for Missing and Exploited Children will help organize volunteers who've offered to help look for Aarone Thompson. She's been missing since Monday afternoon.

Police say she disappeared after something happened at home that upset her. Police also say their search was delayed by about 90 minutes because of a miscommunication with the girl's father.

Aaron Thompson reported that his daughter was a runaway and it was only after he came down to police headquarters to fill out a report that they realized they were dealing with a very young girl.
