DES MOINES, Iowa—An Iowa teenager was found guilty on Thursday of second-degree murder and manslaughter in the deaths of two students that he shot at a Des Moines alternative school earlier this year.
Preston Walls, 19, had been charged with first-degree murder in the deaths, but jurors found him guilty of lesser charges. That seemed to indicate jurors accepted Mr. Walls’ claim that he fired on the students because he feared for his life.
