The Colorado "Mad Bomber"

Colored Red

In 1992, Grand Junction was rocked with three horrifying explosions. Pipe bombs were being planted in random places around the city and targeting no one in particular. Anyone could be the next victim by simply getting into their car or walking in the wrong place. The mystery seemed to life as investigators and ATF agents honed in on one suspect, a loner and electronics enthusiast named James Genrich. James had an interesting story of his own and also had tools in his home that investigators claimed made the bombs. But did they? I review some of the issues with older forensics technique in this no-so-closed case.
