FAIRFIELD, Ohio (AP) -- A southwest Ohio soldier based in North Carolina has been killed in Afghanistan.

The military says 20-year-old Nicholas Olivas of Fairfield was killed Wednesday in Zharay, Afghanistan, when enemy forces attacked his unit with an improvised explosive device.

He graduated from Fairfield High School in 2010 and was an infantryman with a unit at Fort Bragg, N.C.

Former Hamilton mayor Adolfo Olivas tells The JournalNews of Hamilton ( http://bit.ly/JBPbOF ) that his son was trained to be a translator and had been in Afghanistan since February.

Adolfo Olivas says his son loved fishing and hunting and viewed himself as a protector.

He says the survivors include the soldier's wife and infant.
