On Thursday morning, OCSO Capt. James Schueller said an autopsy was completed Wednesday with the results not available yet, however they classified Robinson’s death as a homicide.

Torgerson said based on their findings, a person of interest was identified and officials began working leads including making contact with the person of interest’s family and asking for assistance in having the person come meet with investigators.

The person was brought to the Law Enforcement Center on Wednesday night by a family member and was taken in for questioning. At the conclusion of the session, the person of interest declined to give a statement and was placed under arrest.

As a result, the suspect has been identified as Mustafa Rahshad Bush, 39, of Rochester, who has been charged with 2nd-degree murder in the death of Robinson. Additional charges may be forthcoming as further evidence is reviewed and processed.

Olmsted County Attorney Mark Ostrem, said Bush is currently on supervised release from the Department of Corrections.

A look at Bush’s previous criminal history includes a conviction in 2006 of 1st degree sale of drugs and again 2011 for the same charge. These both took place in Hennepin County, MN.

In 2006, Bush was convicted of 2nd degree murder in the killing of Corey Richardson at Richardson’s northwest Rochester home. He is currently on supervised release after serving two-thirds of his sentence in prison.

“I think it’s way, way, way too early to comment about whether or not that information would be used at all in this case,” Olmsted County Attorney Mark Ostrem said about Bush’s prior conviction impacting possible charges in Robinson’s death.

In 2006, Bush was sentenced to 20 years for his role in the murder of Cory Richardson. He was released from prison March 30, 2020, and was on supervised release at the time of Robinson’s death.

Ostrem said Bush is scheduled to make his first court appearance sometime next week.

A GoFundMe page has been setup to cover funeral arrangements and memorial service for Robinson.
