Brittany Zimmermann Investigation

During the course of the investigation into the murder of Brittany Sue Zimmermann Madison Police detectives were able to determine a 911 call for service was made from Zimmermann's phone to the Dane County 911 center on April 2nd, 2008. That day the MPD brought this call to the attention of the Dane County 911 Center. Also on this day Command Staff from MPD requested that the 911 Center not release information pertaining to this call. The request for non-disclosure has been reviewed throughout the investigation and is currently in force.

The MPD investigation also revealed that this was not an accidental 911 call, it was not an intentionally erroneous call, nor was it a hang-up call.

To protect the integrity of the Zimmermann case the exact contents of the open-line 911 call cannot be revealed. It would be accurate to state that there is evidence contained in the call, which should have resulted in a Madison police officer being dispatched. That would have been consistent with both Madison Police Department Policy, and national 911 standards. The 911 center did not call back to the telephone number, MPD was not notified of the call, and no officer was sent.

Shortly after the homicide Madison Police Chief Noble Wray recommended that the Dane County 911 Center conduct an internal investigation into what happened with this 911 call.

The MPD has enjoyed a good working relationship with the Dane County 911 Center, and is committed to continuing that relationship as we look to uphold public trust and confidence in our law enforcement system.

Because of the ongoing nature of this criminal investigation the content of the 911 call is not being disclosed at this time.
