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.
