Not clear whether Virginia Gunman is dead, reports he had a 23 page manifesto

Law enforcement confronted Vester Flanagan on Interstate 66 and Flanagan shot himself, officials tell CNN. It is not clear whether he was killed or injured.
ABC News reported that it has received a fax containing a 23-page manifesto from someone named Bryce Williams, the news outlet tweeted. The document has been handed over to investigators, ABC said.
Virginia Tech, photographer Adam Ward’s alma mater, said in a statement, “It is shocking and deeply saddening for this community to be again struck by gun violence. We deplore this senseless violence, now seemingly commonplace in our society.”
One of Ward’s professors, Robert Denton, added, “Adam was a delightful person. He worked hard — you could tell he loved what he was doing. He wasn’t afraid to pitch in and do whatever was necessary for the broadcast. He did whatever was needed with a smile and with grace. He was simply a very nice young man and very professional.”
