Deputies and Southeast Rural Fire were called around 11pm about an explosion.  According to Chief Deputy Ben Houchin, after the fire was put out, investigators soon found out several homemade explosive devices were used. Fortunately, no one was hurt and no structures were damaged. “This act was stupid,” Houchin added.  “Could have caused another huge fire.” The fire did burn some grass in the area but nothing widespread.  There continues to be a heightened alert for fires because of the dry conditions. If you have any information about this case, call the Lancaster County Sheriff’s Office at 402-441-6500 or Crime Stoppers at 402-475-3600.
