Following the publication of this story, Sandra McElroy acknowledged to TSG that she is "Witness 40." Voicing concerns for her minor children, McElroy said that she directed them to delete their Facebook accounts, adding that she has done the same. "After I speak with the prosecutor, attorney, and Police if they say its alright I will call you," she said. McElroy subsequently asked to have an off-the-record conversation, a request to which a TSG reporter agreed.

DECEMBER 15--The grand jury witness who testified that she saw Michael Brown pummel a cop before charging at him "like a football player, head down," is a troubled, bipolar Missouri woman with a criminal past who has a history of making racist remarks and once insinuated herself into another high-profile St. Louis criminal case with claims that police eventually dismissed as a "complete fabrication," The Smoking Gun has learned.

In interviews with police, FBI agents, and federal and state prosecutors--as well as during two separate appearances before the grand jury that ultimately declined to indict Officer Darren Wilson--the purported eyewitness delivered a preposterous and perjurious account of the fatal encounter in Ferguson.
