Bill and Shirley Carter made a lifetime of memories at their home in Lacona. Up until the day the 68-year-old was shot to death on June 19, 2015...

Almost a year later, Carter admits that he has given up hope there will be "Justice for Shirley"...

Carter claims his own son killed his wife. Earlier this year, he and his two other children filed a wrongful death suit alleging Jason Carter is responsible for their wife and mother's death.

Jason Carter's attorney called the claims made in the civil suit "outrageous."
