The Rev. Al Sharpton is expected to appear in North Charleston and attend a vigil for Walter Scott, the black driver who was fatally shot by a white police officer after he fled a traffic stop.

Sharpton is expected to preach Sunday at Charity Missionary Baptist Church before attending a vigil near the scene of the shooting.

Scott was shot April 4 and former officer Michael Slager initially said he fired after a tussle over his department-issued Taser. Witness video showed that Slager fired eight times as Scott ran away. Slager was fired and has been charged with murder.

The shooting sparked outrage as another instance of a white law officer fatally shooting an unarmed black man under questionable circumstances.

Hundreds gathered in Summerville on Saturday for Scott's funeral.
