(MSNBC) — A jury found Virginia Tech negligent Wednesday for delaying warnings in response to the first shootings in the 2007 massacre that left 33 dead on the campus.

Jurors returned the verdict in a wrongful death civil suit brought by the parents of two students who were killed on April 16, 2007, in the most deadly mass shooting in modern U.S. history. Jurors deliberated for 3 ½ hours.

The families of Erin Peterson and Julia Pryde, each awarded $4 million, said the two might be alive today if Virginia Tech police and administrators warned the campus of two shootings in a dorm 2 ½ hours before Seung-Hui Cho ended his killing spree, then killed himself.
