Jurors in the case of a white police officer, Michael Slager, who shot and killed African American Walter Scott in the back, could not reach a unanimous verdict, prompting the judge to declare a mistrial.

The shooting was caught a bystander's cellphone video and shocked the nation.

The jury deliberated for nearly 22 hours over four days whether to convict Slager of murder or voluntary manslaughter. A Judge called it "the longest [deliberation] I've ever been involved in."

Slager could face a lifetime in prison if convicted of murder. The voluntary manslaughter charge could bring a sentence of up to 30 years.
