The progression of the federal and state investigation into the death of pizza deliveryman Brian Wells:
Aug. 28, 2003: A bomb locked around Wells explodes, killing him, after he robbed the PNC Bank branch in Summit Township, south of Erie. Television station WJET captured audio and video of Wells as he sat handcuffed in front of a state police car.
Sept. 2, 2003: Officials release photographs of the collar and the lock, believing someone may recognize the device. Officials receive hundreds of calls.
Sept. 25, 2003: Investigators release photos of a strange cane-shaped firearm found in Wells' car and offer a $50,000 reward for information in the case.
Sept. 27, 2003: A law enforcement source says William Rothstein, who told police he had helped a woman hide the body of her roommate in his freezer, wrote a note in which he proclaimed his innocence in the Wells' case. He had lived next to the stone road where Wells delivered his last pizza, prompting speculation he may have been involved. The FBI found no link between the two cases.
Feb. 10, 2004: The FBI releases sections of the nine-page note found in Wells' car. The note reveals a list of rules and a threat that the man would be "destroyed" if he failed to complete his mission.
Feb. 25, 2004: The coroner rules Wells' death a homicide.
July 30, 2004: Rothstein dies of cancer.
