The Pizza Bomber case sent shockwaves locally and around the world.
Now it's become the main focus of a class at Gannon University.
Brian Wells, a Pizza delivery man sent to rob a bank, was killed when a time bomb strapped to his neck, exploded.
Was he part of the scheme or was he set up?
It's one of many questions addressed in a new online course offered at Gannon.
"What we decided to do was take my investigative concepts course that I teach regularly here at Gannon University and attach the pizza bomber case to it, utilizing it as a case study," assistant professor Jerry Clark says.
The six week course is the first ever "Massive Open Online Course," also known as MOOC.
It's open to the public and free.
From Australia to Africa, hundreds of people around the world have enrolled in the class.
Professor Clark says the turnout has been overwhelming.
"I teach the students how to respond even when they arrive on scene, all the way through the culmination of the case, resulting in trial," Clark says. "I think that the students all leave there with the satisfaction of learning something new in the investigative process."
The class officially began last week but school officials plan to offer it again very soon.
