Dunno

Eddie Sherman's answer was immediate, but he spoke the words slowly, as if having difficulty remembering.
"Wasn't nobody near her. But I thought mebbe I saw somebody running away."
Sheriff Cole's eyes narrowed.
"Who?"
"Dunno. Somebody."
Mickey intervened: "Think, Sherman, or dya want me to think for you?" The threat was vague, but it was there.
"Sheriff, I was kinda shocked, y'know? I dunno. A kid."
"A kid?"
Sherman spread his arms, "I dunno."
"Who'd you think it could have been, Eddie?"
"Dunno for certain, Sheriff. But it sure looked to me as if it could have been Zeke McGinley."
