Two people were killed and 16 were critically injured in northeast Nebraska on June 16 in a freakish weather catastrophe, when two separate tornadoes touched down about a mile apart.
According to NBC News, the first tornado tore down power lines and leveled a daycare center, and rescue workers were still pulling people out of the wreckage when they learned that a second tornado was hurtling toward them. That twister proceeded to level much of Pilger, a town of 350 about 75 miles west of Omaha.
