The 911 call from a UW-Madison student's cell phone the day she died included sounds of a woman's screams and a struggle.

Search warrants obtained by the Wisconsin State Journal include police statements that describe the call by Brittany Zimmerman on April 2, shortly before her fiance found her dead at their apartment.

Madison police and Dane County officials have refused to disclose the content of the call, which was mishandled by the 911 center. Authorities have said a dispatcher apparently failed to hear sounds on the other end and did not send police to the apartment.

The warrants have been sealed and resealed by judges at the request of police and Dane County prosecutors, but the latest seal on all of them expired last week.
