Ferguson officials set to address resignation of officer who killed unarmed 18-year-old

Ferguson officials plan to address the resignation of a police officer who fatally shot 18-year-old Michael Brown, as his parents prepared to attend a church service where civil rights activist the Rev. Al Sharpton was scheduled to preach.

Darren Wilson, who had been on administrative leave since the Aug. 9 shooting, resigned Saturday, effective immediately, according to his lawyer, Neil Bruntrager, who declined further comment. An attorney for Brown's family didn't immediately return messages seeking comment.

Stephanie Karr, city attorney for Ferguson, says officials planned to make a statement on Wilson's resignation Sunday. Karr earlier this week said Wilson had been on paid leave pending the outcome of an internal police investigation.
