public-journalism Web site

A teenager may be behind a bogus story posted on CNN's public-journalism Web site earlier this month that said Apple CEO Steve Jobs had suffered a heart attack and was being rushed to the hospital.

The U.S. Securities and Exchange Commission immediately launched an investigation into the false story posted by "Johntw" on CNN's iReport.com after the news caused Apple's stock to plunge nearly six percent that day, from $106.50 to $94.65.
