As the war continued to take its toll, parents in Live Oak and Gilroy learned this week that their only sons had been killed in Iraq. Marine Lance Cpl. Jeramy Ailes, 22, of Gilroy was killed Monday in Al-Fallujah by small arms fire.``They had finished mopping up in Fallujah and they went back to double-check on some insurgents. From what we gathered, somebody playing possum jumped up and shot him,'' said his father, Joel Ailes, who learned of his death Monday evening. ``It's extremely hard.''
