For the past several weeks there have been backstage attacks during every episode of Impact where a card with a circled "X" was placed by each victim. Fallah Bahh, Sonjay Dutt, Jimmy Jacobs, and Joseph Park have been taken out since these attacks started.
Petey Williams was recently seen at two of the incidents and Sonjay Dutt had him arrested in the belief that he was the attacker. As the police officer took Williams away from the group, the real culprit ended up beating down Williams. He then placed a card by Williams and told the camera man to call the police.
Although his name isn't officially known in Impact quite yet, he is known elsewhere as Killer Kross (Kevin Kross).
Debuting in 2014, Kross has worked previously for Global Force Wrestling, Lucha Underground (in dark matches), and more recently for AAA. In AAA, he's in a stable called MAD alongside Jeventud Guerrera and Teddy Hart.
