Breonna Taylor's boyfriend, Kenneth Walker, speaks to Gayle King one year after her death
Kenneth Walker's life was changed just over one year ago when Louisville Metro Police officers killed his girlfriend, Breonna Taylor, in her home and arrested Walker for firing in self-defense. The charges against him have now been permanently dismissed, but he exclusively told "CBS This Morning" co-host Gayle King that he's still struggling to adjust to life without Breonna.
