| The men were killed on Monday when their unit, part of the 
				NATO-led International Security Assistance Force, clashed with 
				insurgents and were mistakenly hit by their own forces in an air 
				strike, local police chief Ghulam Sakhi Roghlewanai said.
 Justin Helton, 25, a U.S. Army bomb specialist from Beaver, 
				Ohio, was among the dead, his cousin, Mindy Helton, said in a 
				telephone interview.
 
 Aaron Toppen, 19, of Mokena, Illinois, also was killed in the 
				air strike in Afghanistan, said Jennie Swartz, who was acting as 
				a spokeswoman for the Toppen family.
 
 Helton, who had been in the service since 2010, was engaged to 
				be married, Mindy Helton said. Military representatives on 
				Tuesday notified Helton's family of his death, she said.
 
 "We are just exhausted," Helton said. "Yesterday was 
				overwhelming and we are waiting to hear what happens next."
 
 The Pentagon has said investigators were looking into the 
				likelihood that the deaths were caused by friendly fire.
