ROCK SPRINGS, Wyo. (AP) -- A suspicious device at a southwest Wyoming power plant turned out not to be a bomb, but it might have hurt a mosquito or two. Security guards spotted the object at the Jim Bridger Power Plant around midnight Wednesday. The device had wires connected to a small battery. A bomb squad was called out to the coal-fired power plant. Sweetwater County sheriff's officials say bomb experts looked over the device and even X-rayed it. It was a mosquito trap. Weed and pest officers routinely put out the traps to check for mosquitoes that carry the West Nile virus.
