I didn't know the guy Blind Pennsylvania man dies after accidentally setting clothes on fire with microwave (VIDEO) James Shaffer, 68, reportedly suffered fatal burns after he put a wet towel in the microwave to warm it to ease a knee pain at his Stonycreek Township home on Tuesday night. BY Lee Moran NEW YORK DAILY NEWS Monday, January 19, 2015, 8:30 AM WJAC-TV James Shaffer, 68, accidently burned himself fatally after he tried to microwave a dry towel for his aching knee in his Stonycreek Township, Pa., home. A blind Pennsylvania man died after he accidentally set his clothes on fire while trying to warm up a wet towel in a microwave. James Shaffer nuked the rag that he wanted to put on his sore knee at his Stonycreek Township home on Tuesday night, reports WJAC TV. But the 68-year-old didn't realize it was on fire as he removed it from the machine. He placed it on his leg, and it promptly set his clothes on fire. Shaffer, who's lived alone for the last 25 years, managed to put out the flames with water from his bathtub. He then dialed 911 and was rushed to hospital by paramedics — who said he spoke to them "calmly" during the entire journey. "He was very apologetic, he was telling us every couple of minutes that he was sorry, he should have known better," David Ream, Oakland Fire Department's deputy chief, told WJAC TV. "He was very, very calm for the situation we had at hand. We were shocked. He was talking to us, just normally like we're talking back and forth, with no issues," he added. Doctors discovered that Shaffer had suffered burns to 80 per cent of his body. He was transferred to a specialist burns unit in Pittsburgh. But tragically he died in hospital Wednesday morning. The official cause of death was smoke inhalation. Investigators said that using a microwave to warm a towel can cause it to burn within 15 seconds. And that is what they believe happened to Shaffer. Neighbors paid tribute to "one of the nicest and most intelligent men they'd ever met." They added that, while his family checked on him daily, he was more than capable of living by himself.
