MADISON, Wis. (AP) -- A judge is refusing to immediately release a recording of a 911 call from a slain University of Wisconsin-Madison student's cell phone.
Dane County Circuit Court Judge Richard Niess says it would be irresponsible to make the tape public before he hears arguments from police on how it could hurt their search for whoever killed 21-year-old Brittany Zimmermann in April.
He scheduled a hearing on that issue for next week.
The call has been the source of public controversy for months. A warrant made public last week says the call contains the sounds of screaming and a struggle.
Dane County 911 center officials say the operator could not hear those sounds, did not call back the number as required and did not send any officers to investigate.
A group of media outlets is seeking access to the tape.
