Sandra Walker's husband, Glen, was killed in a 2011 car accident. Tamara Matthews, whose out-of-control minivan slammed into the Walkers' vehicle, lost her own son in the accident as well.
Last week Matthews pleaded guilty to her role in the crash, and in a touching act of forgiveness, Walker hugged Matthews in court.
Walker told her "You need to let yourself out of the prison you put yourself in." She explained "I want her [Matthews] to be okay, I want her to know she can be okay."
Walker talked about her forgiveness with HLN On the Case's Vinnie Politan.
