Mensah killed Cole on Feb. 2 2020 following a foot pursuit at Mayfair Mall, during which Mensah said Cole pointed a gun at him. Attorneys representing the Cole family argued that Cole shot himself in the arm as he ran, causing him to fall to the ground. At one point during testimony, four fully uniformed Wauwatosa officers sat on the far side of the courtroom in full view of the jury. When Schleis, who is still a Wauwatosa officer, later took the stand and heard the clip, he denied having said that. Mensah testified that after hearing the first gunshot as he chased Cole, he pulled out his own weapon.
