AFGHANISTAN -- A 23-year-old former Clearfield man was killed in combat last Sunday in Afghanistan.
   
    Michael Lehmiller's death comes amid a rise in insurgents' attacks, more common in Iraq, targeting American troops in Afghanistan.
   
    The roadside bombing that destroyed the Humvee in which the young sergeant was riding near Baylough, in southern Afghanistan, left three other U.S. soldiers' families in mourning as well.
   
    Lehmiller attended high school in Clearfield for about a year in the mid-1990s but lived with his mother in Florida and South Carolina for most of his life.
