The pizza bomber video depicts how a man who was dressed as a delivery boy robbed a bank and later died in a blast. 

Marjorie Diehl-Armstrong, a 68-year-old woman who was convicted in a 2003 Pennsylvania bank robbery plot, passed away on Tuesday at the Federal Medical Center in Carswell, Texas. 

She was serving a life sentence plus 30 years for her involvement in the failed robbery in Erie, Pennsylvania, which resulted in the death of 46-year-old Brian Wells. 

The woman was found guilty in 2010 of armed bank robbery, conspiracy, and using a destructive device in a crime of violence for bank robbery.

In August 2003, Wells, who was dressed as a pizza delivery man, entered a PNC bank with a bomb locked to his neck. 

He escaped with $8,702 but was stopped by police shortly after. The bomb exploded before the arrival of the bomb squad, killing Wells. 

Prosecutors believed that five people were involved in the crime and revealed that they thought Wells was part of the plot initially but probably did not realize the danger he was in until the last moment.

Diehl-Armstrong and three other men were determined to be involved in the plot. One of the men had died of cancer before trial, Diehl-Armstrong killed another, and the third pleaded guilty and testified against her. 

The defense argued that Diehl Armstrong’s mental disorders and a hostile relationship with at least one of the plotters made it unlikely that she participated in the crime. At the same time, she believed she had been framed.

William Rothstein, a handyman and substitute science teacher, was said to have constructed the bomb collar using two egg timers supplied by Diehl-Armstrong. 

He later died of cancer. Kenneth Barnes, another accomplice, pleaded guilty and is serving 45 years in prison. He testified that Diehl-Armstrong planned the heist to pay him to kill her father.

Before her conviction in the bank robbery plot, Diehl-Armstrong had already been serving seven to 20 years for killing her live-in boyfriend, James Roden. 

She had claimed that she killed him because he was abusive. The U.S. Attorney, Marshall Piccinini, maintained that Diehl-Armstrong killed Roden more than two weeks before the robbery as he was involved in the plot and threatened to reveal it.

The cause of Diehl Armstrong’s death is unknown, as the Federal Bureau of Prisons did not provide a reason. She was serving a life sentence for her role in the infamous 2003 bank robbery plot, which resulted in the death of Brian Wells.
