Another trial in the killing of 17-year-old Alvin Cole by then-Wauwatosa police officer Joseph Mensah began Monday, with attorneys battling over whether Mensah used excessive force when he killed Cole following a foot chase in 2020. Mensah has claimed that Cole pointed a gun in his direction, making him fear for his life and triggering his decision to fire five shots at Cole. Attorney Kimberley Motley, representing Cole and his family, used a projection screen to display a photo of Cole when he was younger. Cole was Mensah’s third shooting over a five-year period at Wauwatosa PD, a fact not shared with jurors. After the first shot went off, Shamsi testified that Cole ended up on his hands and knees, with the firearm still in his right hand.
