According to The First Post:
"The release of a new Meryl Streep movie about a campus killing spree, which was postponed last year after the shooting of 32 people at Virginia Tech, will not be delayed again – despite the recent spate of campus killings, including the gunning down of five students in a classroom at Northern Illinois University on St Valentine’s Day. Dark Matter is based on the true story of Gang Lu, a Chinese graduate student at the University of Iowa who shot and killed five people and paralysed another before killing himself in 1991. In real life, Lu's rage was fueled by his belief that he should have received honours for his doctoral dissertation that were instead awarded to a fellow student."Here is a link to movie's website.
