BOSTON -- The issue of Rolling Stone magazine with Boston bombing suspect Dzhokhar Tsarnaev on the cover has sold nearly twice as many copies as an average issue.

That's according to Adweek, which says people bought more than 13,000 copies of the issue at more than 1,400 retailers from July 19 to July 29. That's more than double the magazine's average sales for previous years.

Some retailers said they would not sell the issue after a public outcry over the cover, which critics said glamorized Tsarnaev.

The 19-year-old has pleaded not guilty in the deadly bombing of the most famous U.S. marathon.

Rolling Stone says the story was part of its "longstanding commitment to serious and thoughtful coverage of the most important political and cultural issues of our day."
