Holly Mullen left on Wednesday after nearly two years at the alt-weekly, the Salt Lake Tribune reports. Neither Mullen nor publisher Jim Rizzi would disclose the reason for Mullen's departure, which she described as a "mutual decision to part ways." Rizzi says Mullen has been replaced by Jerre Wroble, who joined the paper as a copy editor in 2002 and has been managing editor since April 2005.
