MADISON, Wis. -- Dane County and Madison leaders have agreed to address systemic problems at the 911 Center after multiple errors contributed to police not going to a disturbance Monday that left a man dead.

A 911 Call Center report released Friday said dispatchers should have sent police to an incident Monday but did not until after a man was found dead.

Mark Johnson, 37, was found beaten to death at Lake Edge Park in Madison Monday night.

Late Friday, after the release of the 911 Call Center's internal investigation into call handling the night of Johnson's death, Dane County Executive Kathleen Falk ordered all 911 call takers and dispatchers to send police if there is any doubt of a public safety issue or a threat of one.

Falk also continues to push for new police dispatching software and a formal review of why so many police agency policies on dispatching are different.

The latest directives from Falk to the 911 Center comes seven months after the 911 Center came under fire for not dispatching police after a call from University of Wisconsin-Madison student Brittany Zimmermann, who was later found slain.

The Zimmermann family said it can't believe Falk hadn't conducted the review already and that another person is dead.

"It's absolutely incomprehensible," said Zimmermann's aunt, Kim Heeg, of Marshfield. "I'm angry; very angry. I cannot believe after everything that has come up with Brittany's murder and mishandling that occurred with her phone call that again they could do this."

Zimmermann's family said the Johnson's death could have been stopped.

"We're talking about another death. And he clearly, in my mind, could have been saved," Heeg told WISC-TV by phone. "There was plenty of time for someone to be sent."

Heeg said Zimmermann's parents are "heartbroken" and "angry" that a second slaying potentially could have been prevented but wasn't due to 911 Center problems that they said Falk had promised to fix.

"It's unacceptable, the current situation," Falk said Friday of the new report and mistakes.

On Friday, Falk made more promised to shore things up and eliminate similar mistakes at the 911 Call Center in light of a 911 internal report that found two clear operator mistakes surrounding calls placed before police found Johnson.

The first call, the report said, was handled properly as low priority. That doesn't lead to automatic police dispatch.

But the report said after a second call reporting an escalating disturbance at Lake Edge Park, a seven-month operator still on probation failed to upgrade it to a higher priority call, a move that would have triggered a police dispatch about 90 minutes before the slaying victim was found.

The report also said the second call was mistakenly canceled early.

"Because you can't ever completely eliminate human error, what you can do is try to eliminate as much as possible for it," Falk said.

But Heeg said she isn't very sympathetic.

"If (I) was living in Madison right now, I have to say I would be pretty frightful, because I think we've seen that when you call 911, you might not get help," Heeg said.

Heeg said the Zimmermann family dropped its federal lawsuit against the county but is pursuing it in state court.

Heeg said the Zimmermanns' hearts go out to Mark Johnson's family and friends and they are saddened they are going through a similar tragedy.

Meanwhile, county officials are trying to dispel fear that the 911 Center doesn't work properly.

Falk has issued an immediate directive Friday to operators that no matter what a police agency's policy is, if dispatchers think it is needed, they should send out police.

On Thursday, a consultant released an independent audit that said the 911 Center is short nine operators, and dispatchers said they are extremely short staffed and highly stressed.

Mayor, Police Chief React To 911 Report

Both Madison's mayor and police chief said that as they read the 911 Center report released Friday that the ultimate problem was that the second call wasn't correctly coded to a higher priority, meaning officers would have automatically been sent.

The report said that the call was marked on a waiting list at a lower priority, and officers were not sent because of Madison Police Department guidelines.

Police Chief Noble Wray said shift change policies, which a dispatcher told WISC-TV might have affected officer availability that night, had nothing to do with the response to the incident.

"The change in shift policy has nothing whatsoever to do with this incident, nothing. There's not a connection at all, and I want to be clear about that because the change of shift policy does not start to take effect until 10 o'clock, and even when that takes effect, there are still officers to send," Wray said.

The two calls to the non-emergency line came in during the 9 p.m. hour. The mayor said he is happy the report was completed quickly and that he seeks to restore confidence in the 911 Center.

"What we need to do is to get at the root of the problem and move forward together. And I talked to the county executive this afternoon, she and I agreed that right after our respective budgets, we're going to get to work on a long-term contract," said Mayor Dave Cieslewicz.

The city currently has an interim contract with the 911 Center, as its 20-year contract expired recently.
