Patricia Ann Cosby, 53, was fatally wounded on October 9, 2017, during a chaotic attempt to stop a pit bull attack on a Detroit street. Neighbour Michael Lewis Williams, 61, who held a concealed pistol license, said he heard Cosby’s screams and fired his handgun to fend off the animal. The bullet missed the dog and struck Cosby; the Wayne County Medical Examiner’s Office ruled her cause of death a single gunshot wound.

Cosby’s father publicly expressed that he did not believe Williams should be charged, saying the neighbour was trying to save his daughter. Detroit police initially did not confirm whether charges would be filed. In March 2018 the Wayne County Prosecutor’s Office arraigned Williams on careless discharge of a weapon causing injury or death.

Are there witnesses or additional details about the moments before the shooting that could clarify what happened?
