"With a high-profile columnist, especially with the credentials present in this case, it is not first nature or even second nature to ask them if the person they're writing about actually exists," Rodriguez said. "Columnists are given more latitude in their writing style. It's more personalized. They share their voice and their views with the community."

The detailed descriptions that flowed through the narratives also lent a sense of credibility, he added.

"As an editor, when you get that many details from a writer, you're less likely to question the authenticity," Rodriguez said. "She even described the way the cat's tail was curling."

Another factor came into play. Unlike news stories, columns usually are not illustrated with photographs of the subject. That may change, according to Rodriguez.
