MADISON, Wis. -- The Dane County Board's Executive Committee on Thursday evening approved a second audit of the county's 911 center in five years.

The move comes in response to the controversy surrounding a 911 call in early April.

University of Wisconsin-Madison student Brittany Zimmermann, 21, was found slain in her campus-area apartment in April. The county's 911 center received a call from Zimmermann's cell phone sometime prior to her body being discovered, but officials have said that a dispatcher mishandled the call.

County board members said they will have a private firm complete the audit into the 911 Center.

A national public safety organization declined to be a part of the study, saying it didn't have adequate resources.

The county had an audit done at the 911 Center in 2004, so some of the debate from the public at Wednesday night's meeting was over the need for another audit.

The county said that some recommendations from the 2004 audit have been implemented. Some said that a new study will build on current knowledge.

"What (a new audit) can tell us is, 'Have the changes been made that were recommended? Are we following those policy changes? What staffing increases may be needed from that audit to this audit?'" said Dane County Board Chair Scott McDonell.

Rosemary Lee, of Madison, said that she supports a new audit of the 911 center.

"It is time for the media to stop the hype and let the audit results show the true situation of our 911 center and what must be done to improve it," Lee said.

McDonell said that a new audit could cost anywhere from $50,000 to $100,000.

Currently, there is roughly $65,000 left in the audit budget for the year, WISC-TV reported.

Others at Wednesday night's meeting said that spending the money on another audit isn't necessary.

"We can't restore public confidence by throwing more money at this program. That won't do," said Bill Rowe, of Madison.

"They aren't budgeting the money; they aren't giving the resources, and we don't need a new study. We've got a study -- implement the thing," said Gary Berliot, of Madison.

The county will now put out a call for proposals. Officials said they hope to have the audit begin this summer and have it completed before the next budget cycle.
