I can actually see one possible scenario where that day 2 article was posted by Bishop.
He targeted Mason. He saw his target visit Hopgood and Mason claimed bus driven. He gave out an investigator result in case the kidnapper was responsible for the swap and an escort blocked Hopgood, so that the mafia would not kill the person who was swapped with Mason immediately as they could still be a witch or a ghost. He added some FoS to Mason in case she lied about being bus driven.
Bishop did know his WIFOM. He was using invisible text background to trollclaim spree killer.
