Wisconsin police officials have outlined that a couple was electrocuted while attempting to use a dangerous wood-burning technique that has become popular on social media.

The deceased, 44-year-old Tanya Rodriguez and 52-year-old James Carolfi, were killed earlier this month after attempting a dangerous art form challenge known as Fractal Burning.

This challenge is a technique in which high-voltage electricity is used to burn lightning or a tree-like pattern into wood that has been soaked in a chemical solution.

Marathon County officials and fire marshals and other agencies concluded that Rodriguez and Carolfi died by accidental electrocution while attempting to use an art technique called “fractal wood burning” prior to the fire.

In addition to the findings, Authorities stated their deaths have been deemed “accidental in nature” and foul play has been ruled out.

“Through the investigation, it was determined that the fire started in the garage before spreading to the home. We believe that the fractal wood-burning equipment that caused the electrocutions likely caused the structure fire,” the Marathon County Sheriff’s Office outlined.

Meanwhile, the Sheriff’s County office has issued a stern warning to TikTok users to desist from this dangerous practice which they said gained popularity due to viral videos on social media.

“The Marathon County Sheriff’s Office wishes to alert citizens of the dangers of fractal woodburning, an art form that has gained popularity on social media sites such as TikTok, Facebook, and YouTube,” the statement outlined
