Connecticut NAACP officials said they are investigating police use of a stun gun on an injured man who later died. Authorities identified the man Tuesday as 43-year-old Noel Mendoza of Meriden. NAACP State Conference President Scot Esdaile said at a press conference Tuesday that the civil rights group is demanding explanations about why Mendoza and two other people have died since 2008 after Meriden police used stun guns. State Police are investigating the incident Sunday night outside the police station. Authorities said Mendoza was bleeding from his hands, acting irrationally, and high on drugs. Officers said he became combative and was subdued with a stun gun. Mendoza died at a hospital later that night.
