On the evening of Tuesday, June 9, 2015, a shooting at Rumbold Park in the North St. Louis neighborhood killed 27-year-old Jennifer Denise Dorsey. Dorsey was at a playground near North Market Street and North Spring Avenue with family and friends when gunfire erupted; she was struck in the head and later pronounced dead at a local hospital.

Three men at the scene were also wounded — two men in their mid-20s and one man in his mid-40s. One suffered a critical leg wound; the other two were listed in stable condition. Investigators recovered at least 15 shell casings in the park and asked the public about two vehicles seen leaving the area on North Market Street.

Does anyone who was in that neighborhood that night or who remembers those vehicles have information that could help investigators?
