Gannon was first reported missing Jan. 27 by his stepmother, Letecia “Tecia” Stauch, who said Gannon left to go to a friend’s house in the afternoon. Authorities called him a runaway when it first asked the public for help finding him. But the sheriff’s office announced Jan. 30 that Gannon was considered a missing and endangered child because of the time he had been gone, his age and his reliance on medication.

The FBI and other agencies, including the Douglas County Sheriff’s Office, have joined in the search for Gannon before search efforts were suspended last Friday.
