In a startling twist to yesterday's story about a South Korean worker who was killed by his cell phone, it turns out that the death is now being blamed on his co-worker, who confessed to making up the story after striking the victim with a drilling vehicle, South Korean police said Friday, The Associated Press reports.

Apparently what happened is that initial reports blamed the melted phone and battery in the dead man's shirt pocket. But "after preliminary autopsy results suggested damage to Seo's internal organs was too great to be caused by a cell phone explosion," police then questioned the colleague who first reported Seo's death.

That man later confessed to the accidental killing, leading us to wonder exactly what he did next to melt the phone and disguise the accident. The report only said that the man moved the drilling vehicle away from the scene, but didn't go into any further details.
