On August 28, 2003, pizza delivery driver Brian Wells robbed a PNC Bank at the Summit Towne Center on Peach Street near his hometown of Erie, Pennsylvania, with a bomb-like collar device already locked around his neck. He passed a teller a note demanding $250,000 within fifteen minutes; unable to open the vault that quickly, the teller gave him $8,702. A witness called 9-1-1 minutes later. Police arrested him in a parking lot about fifteen minutes later as he worked through handwritten 'scavenger hunt' instructions found in his car describing timed tasks meant to disarm the device. The bomb detonated at 3:18 p.m., roughly three minutes before a bomb squad arrived, killing Wells within seconds.
The FBI, working with the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Pennsylvania State Police, opened an investigation the FBI itself described as 'one of the most complicated and bizarre crimes in the annals of the FBI.' Investigators concluded Wells helped plan the robbery and knew of the underlying scheme, but believed the device was fake; his family and friends dispute this, saying he was accosted at gunpoint and forced to wear a live bomb. Exactly what happened when the device was attached to his neck was never conclusively established, though evidence indicated a struggle and a gunshot fired to compel his compliance.
In July 2007, federal prosecutors charged Marjorie Diehl-Armstrong and Kenneth Barnes with the crime, naming Diehl-Armstrong as the plot's mastermind. Investigators determined she devised the robbery to raise money to pay Barnes to kill her father for an inheritance she believed he was squandering. Diehl-Armstrong, who had a documented history of bipolar disorder and had previously been acquitted, on self-defense grounds, of a 1984 killing of a boyfriend, was ruled incompetent to stand trial in 2008 and competent again in 2010. On November 1, 2010, she was convicted of armed bank robbery, conspiracy to commit armed bank robbery, and using a destructive device in a crime; on February 28, 2011, she was sentenced to life in prison without parole, and her appeals were denied through 2015. Barnes pleaded guilty in September 2008 and was sentenced to 45 years, later reduced to 22.5 years after he testified against Diehl-Armstrong.
Diehl-Armstrong separately pleaded guilty but mentally ill in January 2005 to third-degree murder and abuse of a corpse for killing James Roden, who had lived with her for ten years, and was sentenced to seven to twenty years; investigators believe she killed him to stop him from telling authorities about the robbery plot. A man who had been romantically involved with Diehl-Armstrong decades earlier and lived near the delivery address, identified by investigators as the bomb's likely designer, died of cancer on July 30, 2004, before any charges were filed against him; he and Wells were both later named in the 2007 indictment only as un-indicted co-conspirators. A second man living at the same address told investigators he had placed the device on Wells and was granted immunity for his cooperation but was never called to testify in court.
Diehl-Armstrong died of breast cancer in prison on April 4, 2017, at age 68. Barnes died in prison of lung cancer on June 20, 2019. In 2018, a woman who knew Wells said in a Netflix documentary that she had given a conspirator his name and delivery schedule in exchange for money and drugs, and that Wells had no advance knowledge of the robbery. Known as the collar bomb case or pizza bomber case, the crime drew extensive national media coverage, including a 2012 true-crime book and a Netflix documentary series.
