MADISON, Wis. (AP) - Police say a University of Wisconsin student called 911 from her cell phone shortly before she was killed but a dispatcher hung up, didn't call back and never sent police.
The police chief in Madison, Wisconsin, says it's too early to know if a better response could have saved 21-year-old Brittany Zimmermann or helped police capture her killer.
Authorities haven't released the content of the call, but police say it should have been enough for the Dane County 911 operator to take seriously.
Zimmermann was found dead in her apartment in what police say was a random crime. They haven't identified a suspect. But they have ruled out her fiance, who found the body and shared the apartment.
The 911 center says it's investigating the incident to decide if employees should be disciplined. A spokesman says he doesn't think "there's anything to apologize for at this time."
