In 1979, a woman had told her friend, Susan Schwarz, that her husband had been beating her. When Gregory Johnson learned his wife was talking about their problems, he accused Schwarz of meddling, grabbed her while she was in the shower, and shot her. His crime was kept a secret by his then-wife until 2012, when she finally revealed everything she knew to police. He was only given 24 years in prison.
