While the package did not have a return address, the contents of the letter referenced various conspiracy theories, including that aliens have launched attacks on earth, which indicated it was likely from Warner, News Channel 5 said. It sounds like they are guessing it was from him. Hopefully there are more conclusive writings from him that indicate a mapping to these beliefs. The agents pulled many grocery bags of items from his home, so I am looking forward to what is in their report.
