Brian Chase, 38, ended up resigning from his job and apologizing to John Seigenthaler Sr., the former publisher of the Tennessean newspaper and founding editorial director of USA Today.
"I knew from the news that Mr. Seigenthaler was looking for who did it, and I did it, so I needed to let him know in particular that it wasn't anyone out to get him, that it was done as a joke that went horribly, horribly wrong," Chase was quoted as saying in Sunday editions of The Tennessean.
Chase said he didn't know the free Internet encyclopedia called Wikipedia was used as a serious reference tool.
He also said he doesn't support more regulations of the Internet, but he said that he fears "Wikipedia is inviting it by its allowing irresponsible vandals to write anything they want about anybody."
Chase said he created the fake online biography in May as a gag to shock a co-worker who was familiar with the Seigenthaler family. He resigned as an operations manager at a Nashville delivery company as a result of the debacle.
