A new Smoking Gun report says "Witness 40" in the grand jury case for Darren Wilson has a history of making racist remarks and was nowhere near the scene when Wilson shot and killed Michael Brown on Aug. 9.

Sandra McElroy testified that she came across Wilson's encounter with Brown as she was on her way to see an old high school classmate. She couldn't find the address and pulled over to smoke a cigarette.

McElroy said she wrote down her account of the events in a journal, which she brought with her to the grand jury trial. Additionally, she told federal investigators that she saw Brown "charge" at Wilson and that the officer then began firing at the teen.

The report leads to more questions about her credibility as a witness in the case. McElroy struggles with her memory because of a previous car accident. She also suffers from bipolar disorder and does not regularly take medication.

Her track record also shows a history of sharing racist posts on her social media accounts. But she attempted to give the grand jury the impression she was working on changing the prejudices she had towards Black people.
The Smoking Gun reports:
McElroy, again under oath, explained to grand jurors that she was something of an amateur urban anthropologist. Every couple of weeks, McElroy testified, she likes to “go into all the African-American neighborhoods.” During these weekend sojourns — apparently conducted when her ex has the kids — McElroy said she will “go in and have coffee and I will strike up a conversation with an African-American and I will try to talk to them because I’m trying to understand more.”

As she testified, McElroy admitted that her sworn account of the Brown-Wilson confrontation was likely peppered with details of the incident she had read online. But she remained adamant about having been on Canfield Drive and seeing Brown “going after the officer like a football player” before being shot to death.
