Suspected members of the clique, the "Jump Out Boys," are said to celebrate shootings and have matching tattoos that are modified based on specific activities.
The design of the tattoo, confirmed by two sources to the newspaper, reportedly includes an oversize skull with a wide, toothy grimace and glowing red eyes.
The recent discovery of a document, which led to the investigation, suggests "the group embraces shootings as a badge of honor," it was previously reported.
One deputy reportedly came forward to admit association with the clique and named others involved.
