Sheri Lindstrom, a middle-aged woman, drew attention to herself last Sunday by coughing repeatedly at a religious service, witnesses said. At key moments of silence during announcements, prayers, and the sermon, Lindstrom allegedly let out a series of conspicuous hacks prompting bystanders to first notice, then briefly acknowledge her existence. “I think I saw her once at a City Council meeting,” said victim Beth Richards, “she kept clearing her throat.” Lindstrom, a lonely woman, was not approached for comment.
