Born on February 26, 1949, Marjorie Diehl-Armstrong was reportedly the main mastermind behind the hair-raising 2003 case, infamously known as the Pizza Collar-bomb case. From a very early age, Marjorie reportedly struggled with severe mental illness, including hoarding and bipolar disorder, as per a report by People.

She was an exemplary academic student before her mental health deteriorated. She completed her master's degree at Gannon College and was also known as a musical prodigy.

However, the woman also allegedly had the nature of a deadly serial killer. In 1984, Marjorie reportedly shot her then-boyfriend, Robert Thomas but the incident was acquitted as it was claimed to be in self-defense. Later on, the woman's husband and a number of other partners passed away under extremely suspicious circumstances.

Marjorie reportedly arranged the entire plot for the Pizza Collar-bomb case. Kenneth Barnes and William Rothstein were also involved in the plan. She provided a kitchen timer for the collar bomb that was tied to a pizza delivery man named Brian Douglas Wells' neck.

She reportedly forced him to rob a PNC bank for $250,000. When the man was apprehended by authorities, the collar bomb exploded, killing him on the spot. Marjorie planned to pay Barnes to murder her own father with the money from the bank robbery.
