CLAYTON, Mo. — A drug case stemming from an arrest made by the Ferguson police officer who killed an unarmed 18-year-old is on hold while a grand jury reviews the shooting.

A judge approved prosecutors’ request Monday to send the case involving an arrest by officer Darren Wilson to a St. Louis County grand jury. But a spokesman for Prosecuting Attorney Robert McCulloch later said that the case is “on hold” until Wilson’s status is resolved.

The suspect’s attorney wants the drug distribution charge dismissed because he doesn’t expect Wilson, who didn’t attend the preliminary hearing, to show up in court.

Wilson received a Ferguson City Council commendation in February for Christopher Brooks’ arrest on a felony pot distribution charge.

A separate grand jury is reviewing evidence in the August shooting death of Michael Brown.

A county judge on Monday approved a request by prosecutors to let a grand jury review a 2013 drug case in which an arresting officer was the suburban St. Louis police officer who fatally shot 18-year-old Michael Brown last month.

An attorney for Christopher Brooks alleges Ferguson officer Darren Wilson “roughed up” his client after he refused to hand over the keys to a locked car parked in his grandmother’s driveway, where police say they found drug paraphernalia and several ounces of pot.
