In the Associated Press article, "3 Dead in Copter Crash on Calif. Reality TV Set," the author used nine different sources to complete the story.
The sources named include a Los Angeles County Fire dispatcher, a Discovery Channel spokeswoman, a statement from the Discovery Channel, a statement from a production company, a spokesman for FilmLA, "Records", a Federal Aviation Administration spokesman, the Polsa Rosa website, and Internet Movie Database. Four of the sources are from specific people and a few are from Internet websites. There are also statements from companies used to cite information in the article.
All of the individual sources are clustered together within the story, which is OK but the author should have used quotes from certain sources, such as the Discovery Channel spokeswoman, in different areas within the article. For example, the story could have ended with a strong comment from the Discovery Channel about the helicopter crash deaths.
The author did a good job of properly citing all of his sources and providing titles with the names or companies, but he did cite one piece of information from "records" without specifying what record it was. Overall, the author used many sources, which helped complete the story, and provided clear titles for sources.
