HOUSTON — New details regarding Tuesday's mass shooting at a Uvalde elementary school came during a news conference Friday from Texas Department of Public Safety Director Steven McCraw.
McCraw said the commanding officer at the school made a mistake in responding, treating it as a barricaded suspect instead of an active shooting situation. You can read those details here.
