iReport 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.

"It is not true. There is no truth to the rumor." That was the terse denial issued by Katie Cotton, vice president of worldwide communications for Apple, in response to a post on CNN's iReport that Apple CEO Steve Jobs suffered a heart attack Friday.
