A jury trial for a Vermont woman who is charged with texting while driving and injuring a pedestrian opened Tuesday. Lawyers in the trial of 19-year-old Emma Vieira argued whether the accident was the result of inattention while Vieira was texting, or whether it was so dark that she could not see the pedestrian. Deborah Drewniak, 52, was struck in August 2011 as she walked her dog in the roadway. The Burlington Free Press said that Drewniak sustained a traumatic brain injury in the collision and that her dog was killed.
