I've never quite understood the whole murder-suicide thing, with the exception of something like the end of The Mist. AdvertisementBut at least anti-gun states like California don't have to worry about someone having a number of guns they can use in a murder-suicide, right? The news release marked the first time sheriff’s officials identified the gunman found dead in the two-story home in the 5400 block of Mill Water Circle in Rancho Cordova. Sheriff’s officials said Vallerga gave a dispatcher his home address and said he was “the shooter” and that he had installed “booby traps” inside the home. Sheriff’s officials said they confirmed Vallerga had previous military experience and possessed numerous firearms.
