Every day for 10 months in 2012, Peter Antioho walked through dense, black smoke from an open burn pit on his Army base in Afghanistan. Human and medical waste, plastic water bottles, ammunition and chemicals were among the materials burned with diesel fuel 24 hours a day. Five years later, Antioho was diagnosed with an aggressive, terminal brain cancer called glioblastoma multiforme. The West Point graduate and Berlin resident was 31 when he was diagnosed, young for this cancer. He was second in command at his base, but now, with symptoms that include memory loss and impaired vision, speech and motor function, he can’t work.
