Gawker:

In a damning new report by the Smoking Gun, a crucial witness in the grand jury deciding whether to indict former Ferguson, Mo. police officer Darren Wilson is revealed as having fabricated her eyewitness account of the altercation between Wilson and unarmed 18-year-old Michael Brown on Aug. 9. “Witness 40,” identified as 45-year-old Sandra McElroy, has a documented history of racist remarks, criminal behavior, and mental illness.

I wish this case was some kind of bizarre anomaly in how these things are handled, but it seems to be pretty “normal.”
