Dane County Executive Kathleen Falk sent a letter of apology to the family of 21-year-Brittany Zimmermann and her fiance early last week after an investigation concluded that the dispatcher who answered a 911 call from Zimmermann's cell phone around the time she was murdered on April 2, failed to call back after being disconnected. Police have also said there were sounds in the call that should've prompted a police response. Falk, who has heard a recording of the call, said she doubts even had they been dispatched, police wouldn't have been able to save Zimmermann.
