Report: 8chan Owner Says El Paso Shooter Didn't Post Manifesto [Updated]

Instagram said Tuesday that a hate-filled manifesto linked to the El Paso shooter wasn't uploaded to the Facebook-owned photo-sharing site as suggested by the owner of a fringe message board where the document was initially discovered.

A spokeswoman for Facebook said it disabled an Instagram account tied to the suspected gunman on Saturday. The account hadn't been active for more than a year, she said.

Instagram is working with law enforcement, she said, and she directed any additional questions to the Federal Bureau of Investigation. The FBI declined to comment.

The statement comes after Jim Watkins, the owner of the 8chan message board, suggested in a YouTube video that the document had been loaded to his site by a different user. Watkins, who appeared in front of an image of Benjamin Franklin, said the site had made law enforcement "aware" of the manifesto when it appeared.

He also suggested -- but didn't state -- that the gunman, who killed 22 in the attack at a Walmart store, had posted the document to Instagram.

"First of all, the El Paso shooter posted on Instagram, not 8chan," Watkins said in the video. "Later, someone uploaded the manifesto. However, that manifesto was not uploaded by the Walmart shooter. I don't know if he wrote it or not, but it was not uploaded by the murderer; that is clear."
