Anthony Warner sent materials about his views to people he knew, federal investigators said Saturday.
Federal law enforcement confirmed the packages were postmarked December 23, just two days before the bombing, and did not have a return address. It was not immediately clear how many packages Warner mailed.
The packages contained nine typed pages of writings and two thumb drives loaded with videos. At least one of the packages contained a letter that began “Hey Dude, You will never believe what I found in the park.”
“The knowledge I have gained is immeasurable,” the letter continues. “I now understand everything, and I mean everything from who/what we really are, to what the known universe really is.”
The letter urged the recipient to watch the videos Warner included on the thumb drives. The letter was signed “Julio,” a name Warner often used when signing emails.
In a statement to The Associated Press, FBI Special Agent Jason Pack said authorities are “aware the suspect sent materials which espoused his viewpoints to several acquaintances throughout the country.”
The bombing happened Christmas morning well before downtown streets were bustling with activity. Police were responding to a report of shots fired Friday when they encountered the RV blaring a recorded warning that a bomb would detonate in 15 minutes. Then, inexplicably, the audio switched to a recording of Petula Clark’s 1964 hit “Downtown” shortly before the blast.
Pack did not release additional details about what the packages from Warner contained.
