A suicidal gunman opened fire at a Reno hospital campus Tuesday, killing one person, wounding two others and sending police on a door-to-door search within the facility amid the chaos. The Nevada Department of Public Safety said the wounded victims were in surgery and one of them is a doctor. The gunman killed himself after the shooting. Reno Deputy Police Chief Tom Robinson didn't say how many shots were fired or what type of weapon was used, and didn't release the identities of the male shooter or the dead and injured. He said, however, that investigators were confident no one else was involved.
