We're learning more about Elliot Rodger's deadly rampage near the campus of U.C. Santa Barbara last month.  

Santa Barbara County Sheriff Bill Brown says Rodger fired more than 50 gunshots, reloading several times to carry out the shootings that left six students dead in Isla Vista.

Brown says the rampage was brief, with the shots fired in less than eight minutes.

Rodger fatally stabbed his two roommates and their friend at his apartment before he got behind the wheel of his car to carry out the shootings.
