Olivia Marie Greenlee was 21 when she was found dead in her car on Union University’s campus in Jackson, Tennessee, on February 12, 2014. A senior music education major, she suffered a single gunshot wound. The scene had been staged to appear as a suicide.

Investigators focused on Olivia’s 22-year-old fiancé, Charles Pittman, a Christian ministries major at the same school. He told police Olivia had shot herself while he sat in the car with her, but inconsistencies and physical evidence undermined that account. Forensic work indicated the shot was fired from 8 to 10 inches away, and surveillance and clothing evidence did not match Pittman’s statements. He was arrested days after Olivia was found and charged with first-degree murder and tampering with evidence; the gun used belonged to a friend who said they did not give it to him.

In August 2015 Pittman pleaded guilty to second-degree murder and tampering with evidence and received a 40-year prison sentence. Does anyone have information about Olivia’s last hours on February 12, 2014, or contacts who knew her or Charlie Pittman?
