ST. LOUIS - A Missouri lawmaker is calling for an investigation of St. Louis County Prosecutor Bob McCulloch, saying he "manipulated" the grand jury in the Ferguson case.

McCulloch said in a radio interview yesterday that some witnesses obviously lied to the grand jury.

State Rep. Karla May is pushing for a state investigation, saying she believes McCulloch helped sway the grand jury into the decision not to indict Ferguson Officer Darren Wilson in the shooting death of 18-year-old Michael Brown, who was black and unarmed. Wilson is white.

McCulloch, who convened the grand jury in August, was interviewed by KTRS Radio in St. Louis. It was his first interview since he announced the grand-jury decision on Nov. 24.

"Clearly some were not telling the truth," McCulloch said.

He made reference to one woman who claimed to have seen the shooting. McCulloch said she "clearly wasn't present. She recounted a story right out of the newspaper" that backed up Wilson's version of events, he said.
