More than six months after David Klotz died outside the Spearmint Rhino Gentlemen’s Club, the Santa Barbara District Attorney’s office concluded their investigation Wednesday-opting not to file any charges in the death. After reviewing video tape of the incident, several eye witness accounts and the findings of two separate though occasionally conflicting forensic pathology experts, the district attorney ruled that there was “insufficient basis in fact or law” to press charges against the two bouncers who forcibly removed the 26 year-old Klotz from the club and physically detained him for some 21 minutes until police arrived.
