Grand Rapids police officer Christopher Schurr took the stand Friday during his murder trial. It was the first time he's discussed Patrick Lyoya's killing.

Three years after Patrick Lyoya was fatally shot by a Grand Rapids police officer, a trial began April 28 for former officer Christopher Schurr. Schurr faces one charge of second-degree murder, to which he's pleaded not guilty.

A Michigan police officer who killed a man with a shot to the back of the head testified in his own defense Friday, telling jurors at his second-degree murder trial that he was "running on fumes" and fearing for his life after losing his Taser during an intense fight.
