An 11-year-old Colorado boy originally reported as a runaway has now been missing for a week.

The El Paso County Sheriff's Office says over 50 people searched for Gannon Stauch in his Colorado Springs neighborhood on Sunday, including representatives of the FBI and the National Center for Missing and Exploited Children.

The sheriff's office says the search's command post was moved to near the county jail in the afternoon because of unspecified information gathered during its investigation.

The sheriff's office announced late Thursday that Gannon was now considered a missing and endangered child partly because of the amount of time he's been gone.
