Eighteen students face charges, including involuntary manslaughter, in the death of Timothy Piazza, a 19-year-old who died after alcohol-fueled fraternity hazing at Penn State University.

In this episode, Nancy Grace and Alan Duke look at what a grand jury found in its investigation of the deadly Beta Theta Pi party.
