Rita Faye McGaha Pennington, 59, was shot dead in her Gaffney, South Carolina, home on Ford Road on June 21, 2014. Her husband, William Dean Pennington, told investigators the 12-gauge shotgun had accidentally discharged while he was cleaning it, striking his wife.

Investigators determined the fatal wound was fired at close range and said the scene was not consistent with an accidental discharge. Prosecutors later argued the scene had been staged and that growing jealousy and suspicion on William Pennington’s part — including testimony that he had spied on Rita at work and tried to pay a security guard to watch her — provided a motive.

If anyone knew Rita or saw anything on or before June 21, 2014, that could help explain what happened, please come forward with information.
