The witness called me to discuss sightings he has been having since 2006 until now all over the state. He has seen multiple numbers of large lighted orbs, the smallest one being 15 feet in diameter, up to 25 or 30 feet in diameter. The first sighting involved a very close encounter with the light, and since then he sees lights following him in his vehicle whereever he travels in Missouri an nearby states. He is a boiler engineer for power plants and does a lot of travel. The balls of light simply appear and dissapear, and do not move away. They start out as a blue color, then change to red, then yellow.
