Did Brittany Zimmerman try and call for help before she was murdered? A story in Madison's weekly Isthmus newspaper quotes law enforcement sources as saying Zimmerman did call 911 communications, but they erroneously concluded the call was a mistake. The sources tell the paper that the 911 center did not dispatch police and did not immediately or accurately inform authorities about the call until after police found her body. They suggest 911 tried calling Zimmerman back, but dialed a wrong number. The director of 911 communications has refused comment, but a press conference has been scheduled for today.
