It appears that prosecutors in Pinellas County, Florida, may have changed their minds about accepting the Red Bull defense being asserted by Stephen Coffeen.
As you may recall, Coffeen is the gentleman claiming that a combination of sleep deprivation and Red Bull caused him to kill his father in December 2009.
Coffeen apparently acted very strangely when police arrived (not that he had been acting normally before that), so there is likely more to the plea than a claimed overconsumption of Red Bull.
