It's a super long report but worth the read. Here is a very small snippet


Sandra McElroy did not provide police with a contemporaneous account of the Brown-Wilson confrontation, which she claimed to have watched unfold in front of her as she stood on a nearby sidewalk smoking a cigarette.

Instead, McElroy (seen at left) waited four weeks after the shooting to contact cops. By the time she gave St. Louis police a statement on September 11, a general outline of Wilson’s version of the shooting had already appeared in the press. McElroy’s account of the confrontation dovetailed with Wilson’s reported recollection of the incident.

In the weeks after Brown’s shooting--but before she contacted police--McElroy used her Facebook account to comment on the case. On August 15, she “liked’ a Facebook comment reporting that Johnson had admitted that he and Brown stole cigars before the confrontation with Wilson. On August 17, a Facebook commenter wrote that Johnson and others should be arrested for inciting riots and giving false statements to police in connection with their claims that Brown had his hands up when shot by Wilson. “The report and autopsy are in so YES they were false,” McElroy wrote of the “hands-up” claims. This appears to be an odd comment from someone who claims to have been present during the shooting. In response to the posting of a news report about a rally in support of Wilson, McElroy wrote on August 17, “Prayers, support God Bless Officer Wilson.”
