Tracey Lynn White Marshall, 47, was found shot to death inside her pickup truck on Ashley Drive in Terrytown, Louisiana, in the early morning hours of December 13, 2015. A passerby alerted authorities after noticing her hair hanging from the truck window; investigators determined she had been shot multiple times. The previous night there had been reports of gunfire in the area, but deputies had not located anything at that time.

Investigators focused on her ex-boyfriend, James Darby, after evidence showed he had been stalking her in the hours before the killing. Prosecutors say Darby followed her after she returned from a date and approached her vehicle while she was on a cell phone, firing multiple shots. Darby was arrested two days later in Tuscaloosa, Alabama, and charged with second-degree murder. The victim was a 10-year veteran sergeant with the Jefferson Parish Sheriff’s Office.

Does anyone have information about Tracey’s last movements that night or about threats she reported in the weeks before her death?
