The Star Tribune used four sources in the story about Josh Ripley, the Andover High cross-country runner. All four sources were people who witnessed the event. Three of the four sources were named, Josh Ripley, the rescuer, Mark Paulauskas, the injured boy, and Jessica Just, Mark's coach. The other source was given a blanket name of other "runners."
The attribution is spread out throughout the article and is presented in a clear and effective way. The author used a good mix of attribution placement, some of the attributions were placed within, while others were placed at the end of a paragraph.
