University of Wisconsin officials are planning to honor slain student Brittany Zimmermann with a ceremony at the campus bell tower on the anniversary of her death.
Thursday, April 2 marks one year since Zimmermann was murdered at her downtown home. Her killer has never been found.
To observe the day, the Carillon Tower bells will toll 21 times, one chime for each year of her life, beginning at 12:20 p.m., the approximate time of her death.
