What began as a quiet surveillance stop on a busy stretch of Interstate 44 in downtown St. Louis turned violent on Tuesday, when police say a driver rammed an unmarked patrol vehicle near Walnut Street, sending two officers to the hospital and landing the motorist in custody.

Driver arrested on interstate

Police identified the driver as Carmetrius A. Sanders. Investigators say Sanders was behind the wheel of a 2011 Chevrolet Malibu when the crash happened at the I-44 and Walnut Street interchange. Officers at the scene arrested Sanders, who is being held without bond, according to FOX 2. Parts of I-44 were temporarily shut down as detectives documented the scene and spoke with witnesses.

Charges and surveillance details

Charging documents filed with the St. Louis Circuit Attorney’s Office list two counts of first-degree assault, special victim, and two counts of armed criminal action against Sanders. Police said the officers were in an unmarked unit as part of a surveillance operation. Investigators allege the collision happened shortly after a suspected hand-to-hand drug exchange, according to FOX 2. The probable cause statement places the incident at the I-44 and Walnut interchange on Tuesday.

What the charges mean under Missouri law

In Missouri, armed criminal action is an unclassified felony that carries a mandatory prison term, which must run consecutively to any sentence for the related underlying felony, when a weapon is used. First-degree assault can be elevated when the victim is considered a “special victim,” a category that includes law enforcement. The possible penalties depend on the level of injury and other circumstances. For detailed statute language and sentencing ranges, see FindLaw.

Highway hazards and what comes next

The crash underscores how quickly surveillance and traffic work on I-44 can turn risky for officers and drivers alike. A recent dashcam rescue on eastbound I-44 showed the same stretch of highway can shift from routine commute to life-or-death scene in seconds.

The St. Louis Metropolitan Police Department and the Circuit Attorney’s Office continue to investigate the case. It was not immediately known when Sanders will be arraigned. Police have not released further information on the condition of the two officers who were hospitalized after the crash.
