Tucson shooting: Arizona police ID gunman, release video after officer stops rampage outside house fire

A man in Arizona is accused of setting fire to a home in Tucson before engaging in a deadly shooting spree that left one neighbor dead and two first responders and a fire captain wounded.

A woman who lived there is presumed dead, as yet-to-be identified remains were found badly burned at the scene. Three children who also lived at the home have since been found safe with relatives.  "Mr. Scarlett has a criminal history that includes serving six years in prison for armed robbery. He also has a history of mental health issues," Magnus said. "There are far too many individuals with violent criminal intent and the means to injure and kill people. Too often, first responders, such as police, fire and emergency medical service personnel become targeted for reasons that are unclear." "Is it a vendetta, the uniform, the authority it represents or just that police, fire and EMS are the ones out in the field responding to crises and dealing with deeply troubled people day in and day out?" the chief continued.
