This long form news feature by Gene Weingarten is a really great example of powerful storytelling. He tells multiple stories of parents leaving their children in cars, a topic people see in headlines and shake their head in disgust and disbelief, and shows how easily a mistake like this can be made.
The story was very well told and though he breaks it up through multiple sub stories, the narrative is still very fluid and tells a complete story. Through the vivid detail and powerful images Weingarten paints, he manages to keep the reader hooked to the very end of this 8,000+ word story.
