ST. LOUIS COUNTY • Members of the Missouri Legislative Black Caucus used a meeting Sunday with Gov. Jay Nixon to vent over the investigation into the Aug. 9 shooting death of an unarmed Ferguson teenager.

The meeting Sunday afternoon at the University of Missouri-St. Louis was closed to the public and reporters, but some legislators said they repeated calls for an indictment of Ferguson police Officer Darren Wilson and for Nixon to remove St. Louis County Prosecutor Robert McCulloch from the case.

“He’s pretending he cares,” said Sen. Maria Chappelle-Nadal, D-University City, who walked out of the meeting after about 10 minutes. “It’s a waste of time. He’s doing this to look good.”

About a dozen legislators attended, including representatives from Kansas City. The caucus’ vice-chairman, Rep. Brandon Ellington, D-Kansas City, called the meeting “productive” but declined further comment.

After the meeting, Nixon said in an interview that he would not replace McCulloch, saying the prosecutor “has a duty and responsibility to do his job, and that’s what he should do.”
