The man Minneapolis police say killed officer Jamal Mitchell last week stood in a federal courtroom nearly a decade ago as the judge who was sentencing him on a gun conviction pushed him to reckon with his crimes.
“I am taking full responsibility for my actions, and I hope to learn from my mistakes,” Mustafa Ahmed Mohamed told U.S. District Judge Donovan Frank at the time, according to a court transcript.
Last week, police say, Mohamed fatally shot Mitchell on a Whittier neighborhood street, the first Minneapolis officer killed on the job in more than two decades. Mohamed, 35, who was then shot and killed by another officer, had by that point spent more than half of his life in and out of serious trouble with the law, according to court records.
At the time of his death, two warrants were active for the arrest of Mohamed in connection with charges that he possessed a gun on a downtown Minneapolis street in summer 2022, in violation of the terms of his sentences for burglaries in 2006 and 2007.
It was April 2015 when Mohamed faced Frank in the federal courtroom in St. Paul. He was being sentenced for felony possession of a stolen gun while in an Eden Prairie apartment garage.

Frank outlined Mohamed’s crimes up to that point, among them the two felony-level burglaries and a charge in Tennessee for being part of a child sex trafficking ring, a case ultimately dismissed against him and others. The judge then encouraged Mohamed to take advantage of the educational and substance-abuse treatment opportunities at his disposal in the federal prison system.
That’s when Mohamed apologized. He hoped to learn from his mistakes, he said, adding: “Thank you, that is all.”
Frank responded: “For reasons I don’t quite understand, I don’t think we have been able to reach you,” with the various convictions and sentences, at times lenient, imposed up to that point.
