Bombings
While attending the University of Wisconsin–Stout and living in an apartment in Menomonie, WI, Helder planned to plant pipe bombs in mailboxes across the United States to create a smiley face shape on the United States map. The bombs, which were packed with BBs and nails, were rigged to explode as the mailboxes were opened. Completed and rigged bombs were found in Nebraska, Colorado, Texas, Illinois and Iowa. In Iowa, six people, including four mail carriers, were injured when the bombs detonated. Ultimately, Helder planted 18 bombs and covered 3,200 miles. He was eventually captured in rural Nevada before he managed to complete the full smile. At the time of his arrest, police were looking for an unknown suspect driving around in a black Honda Accord and newspapers reported that he was wearing a Kurt Cobain T-Shirt. The bombings were heavily covered by the United States media.
