The police chief in Tucson, Arizona, has offered to resign following the death of a man in police custody. Twenty-seven-year-old Carlos Ingram Lopez died on April 21 after police pinned him face-down to the ground for 12 minutes at his grandmother’s house. His family had called the police because the man was drunk and running around the house naked. When police arrived, they wrestled Lopez to the ground and cuffed his hands behind his back. They then threatened to tase him after ordering him to calm down and relax. In police bodycam video, Carlos Ingram Lopez can be heard asking for water and his grandmother. At one point he says, “I can’t breathe.” The Pima County Attorney’s Office is now conducting a criminal investigation of the actions of the officers, who have all resigned.
