On the evening of August 12, 2016, 25-year-old Sigaria Shanklin was shot while driving on Interstate 55 in St. Louis. A vehicle pulled alongside, opened fire, and the bullets struck Shanklin and a male passenger. Shanklin’s car then left the highway and crashed; emergency crews pronounced her dead at the scene. The male passenger survived his wounds, and a toddler in the car was reported physically unharmed.

Authorities arrested a St. Louis man on charges that included first-degree murder, multiple counts of armed criminal action, and assault in connection with the attack. Beyond the initial arrest, reporting on the case provides little detail about the court proceedings or a motive for the shooting, leaving questions about the investigation’s later progress and why the attack occurred.

Does anyone have information about Sigaria’s life, movements that night, or the investigation that could help fill in the gaps?
