A Church Hill boy is listed in stable condition with non-life threatening injuries after he was injured in an explosion. Investigators say the boy was injured when two boys were experimenting with black powder, marbles and a section of electrical conduit, trying to construct a device capable of shooting the marbles at a target set up in the backyard. The Star Democrat reports as the one boy who was injured held the device, the second boy lit the powder with a lighter. The resulting blast was heard miles away. Paramedics arrived on Laysan Teal Court to find the boy suffering with injuries to his left hand and eyes. Anthony Sturgill, a close family friend, had tied a piece of a sheet around the boy’s arm as a tourniquet while they waited for help to arrive.
