FBI reveals parts of note found with victim of necklace bomb

The note contained a drawing of a McDonald's sign and a road map.
ERIE, Pa. (AP) -- The FBI released sections of a note found in a car belonging to an Erie pizza deliveryman killed when a bomb locked around his neck exploded after he robbed a bank, revealing a list of rules and a threat that the man would be "destroyed" if he failed to complete his mission.
Investigators released the nine-page handwritten note Tuesday hoping that someone will recognize the author for the penmanship or the writer's penchant for obsessiveness. They believe the person who wrote the letter also constructed the bomb and a shotgun found with the deliveryman.
What note included
The note -- containing instructions to rob the bank and directions to four separate locations -- was found with Brian Wells when he died Aug. 28 in a parking lot just south of Erie. Besides listing the "rules" in numerical order and a section titled "The Troubleshooter," the writer meticulously included a hand-drawn McDonald's sign with a rock beside it, a copy of a road map, and a sketch of a traffic warning sign.
"If police or aircraft are involved, you will be destroyed. Alerting authorities or anyone else will prevent you from completing the mission," the note read.
Before the bomb exploded, Wells told authorities that he had been forced to rob the bank by someone who locked the collar bomb around his neck. Police surrounded Wells after he robbed a PNC Bank branch in Summit Township and were waiting for a bomb squad to arrive when the device detonated.
Obsessive
In releasing photographs of the note, FBI Special Agent Bob Rudge described the author as having an "obsessive quality" in telling the reader what to say, how to behave and what to feel.
The writer probably conceived the plan over some time -- perhaps years -- and revenge, not money, may have been the primary motive, Rudge said. He refused to elaborate whether Wells may have been the target of revenge, or another person.
Despite the amount of time devoted to plotting out the robbery, Rudge said it would have been difficult to complete all the tasks in the amount of time Wells was given. Rudge declined to say how much time Wells had before the bomb exploded.
"The overall bank robbery plan as outlined in the letter appear to be unrealistic. Nonetheless, because of the time and effort he invested in this whole scheme -- constructing the collar bomb and the shotgun and preparing the instruction letter -- it is not likely he sat at home waiting to learn how events unfolded," Rudge said, suggesting the suspect was in a position to watch what happened.
FBI agents believe Wells didn't act alone and are leaning toward the theory that Wells was a victim, as he told police. But they haven't entirely ruled out the possibility that he was a willing participant.
"Brian Wells could have known this person but misjudged his level of dangerousness," Rudge said.
The note is the first disclosure of evidence in four months, suggesting earlier appeals have yielded little to solve the case.
Investigators in September released photographs of a triple-banded collar with four keyholes and a combination lock on its heavy homemade clasp and a unique cane-shaped firearm found in Wells' car. A $50,000 reward for solving the case remains unclaimed.
