During a news conference Thursday afternoon, Olmsted County Sheriff Kevin Torgerson said 39-year-old Mustafa Bush of Rochester was booked into the Olmsted County Adult Detention Center on suspicion of second-degree murder. A news release says Bush was brought to the Olmsted County Law Enforcement Center for questioning by a family member Wednesday night and was arrested after declining to give a statement to law enforcement.

Court records indicate Bush was convicted of second-degree murder without intent in April 2007. He was sentenced to a minimum of 10 years in jail, followed by five years of supervised release. Bush has been on supervised release in Olmsted County since March 2020, according to records from the Minnesota Department of Corrections.
