Yesterday. Thats when they found the chemicals. They found a number of chemicals, thins that looked suspicious. They didnt think they had the resources to get those chemicals. We havent been told exactly what the chemicals are but firefighters and the Douglas County bomb squad did not feel comfortable continuing this case. So thats when the fbi and the atf were brought in. Were told they have more so dealing with here. We talked to neighbors and they say they dont really know the people who live at the house and we havent been able to find anyone who knew of any children or teenagers being in or around that house. Police arent saying much about those juveniles that were arrested overnight. But they are saying that this scene and this evacuated neighborhood could go on for several more hours possibly into tuesday morning. We will stay on scene and bring you the latest on a cbs4 news at 10 00. Right now the latest on an orange cloud of smoke released from the suncor oil the refinery. Las
