Carla A. Johnson, 37, was found fatally shot inside her vehicle in Saint Louis, Missouri, on February 25, 2015. Described by people who knew her as sweet and down-to-earth, Johnson worked in housekeeping and attended Vashon High School. Her death came during a year when the city was experiencing a marked rise in violent crime.

The scene yielded few immediate witnesses or physical evidence, and detectives initially faced major challenges piecing together what happened that day. The absence of clear leads left Johnson’s family and the community waiting for answers about who was responsible for the mother’s death.

Does anyone who knew Carla, who saw her around Vashon High School or her workplace, or who remembers that February day have information that could still shed light on what happened?
