Georgetown police charged a 13-year-old boy with possession of a destructive device after authorities found a possible explosive device at his home.

Police say the boy drew pictures in school Friday of what he said were homemade napalm and said he had made a device and it was at his home.

Officers found the device, evacuated homes in the 800 block of East Market Street and recovered the device with a robot.

The device was taken to an open field and disrupted by a water blast from the robot.
