CEDARTOWN — Two police officers were shot, one of them fatally, when a man walked out of the woods Friday and opened fire as the officers investigated a stolen car found beside a road in rural Georgia, authorities said.The suspected gunman, 31-year-old Seth Brandon Spangler, was arrested a few hours later after he again emerged from a patch of woods — this time wearing no clothes — and surrendered, Polk County Police Chief Kenny Dodd said.Dodd said Spangler was wanted for a probation violation in a neighboring county. Now he faces felony murder and aggravated assault charges in the slaying of Polk County police Officer Kristin Hearne and the shooting of Officer David Goodrich, whose bulletproof vest protected him from serious injury."This was obviously not his first run-in with the law," Dodd said at a news conference. "I have no idea why he thought it was worth the life of a police officer who was just doing her job.
