Details are slowly emerging on Thursday’s shooting at Virginia Tech. Police said Friday that the man found dead in a parking lot was the gunman who killed police officer Deriek W. Crouse. Police spokeswoman Corinne Geller told a news conference that authorities have identified the shooter, but won't release his name until they get final confirmation from a medical examiner. Crouse was a 39-year-old Army veteran and the father of five children. The same gun was used on both Crouse and the shooter, suggesting a murder-suicide. Police have not figured out why the shooter targeted Crouse. "That's very much the fundamental part of the investigation right now," said Geller.
