The Milwaukee County District Attorney's Office said it will not press charges against two police officers who used their stun guns as many as 18 times in the death of a naked man in the shower last May.District Attorney John Chisholm made the announcement on Friday, saying there was "no basis to conclusively link Mr. [Adam] Trammell's death to actions taken by police officers."The 22-year-old Trammell, from West Milwaukee, Wisconsin, died in police custody after authorities were called to report a "suspicious male" in an apartment complex at 5 a.mTrammell, who was naked at the time, was allegedly speaking incoherently and flooding an apartment with a shower when police arrived. West Milwaukee and West Allis police said in a press release last year that a stun gun was used on the suspect because he "was uncooperative and combative with officers."He stopped breathing and died at a local hospital, police said.The Milwaukee County medical examiner ruled Trammell's cause of death as excited delirium and the manner "undetermined."The two officers involved were placed on administrative duty for two months before returning to active duty.
