Some witnesses speaking under oath before a grand jury investigating the shooting death of an unarmed black teen by a white officer told lies, St. Louis Prosecutor Robert McCulloch said Friday.

“Clearly some were not telling the truth,” he said in an interview on KTRS 550.

This was the first interview McCulloch has given since the grand jury decided not to indict Ferguson officer Darren Wilson in the shooting death of 18-year-old Michael Brown.

“Early on I decided that anyone who claimed to have witnessed anything would be presented to the grand jury,” McCulloch said. He added that he would've been criticized no matter his decision.

In the interview, McCulloch spoke about a particular witness who “clearly wasn’t present” at the time of the shooting. He said the witness recounted a story out of the newspaper.

This witness and another witness, Sandra McElroy bring up questions about the grand jury’s proceedings.

McElroy testified that she saw the shooting happen and that Brown charged Wilson leading to the fatal incident. However, investigators say there is no way she could have left the apartment complex in the way she said she did.

McCulloch also said he had no regrets making the announcement of the decision at night time. He said the riots were going to happen no matter what time of day the decision was made.

“Those who were bent on destruction, they weren't demonstrators, they're common criminals,” he said.
