Agents of the State Bureau of Investigations for North Carolina discovered that state crime lab analysts either overstated, omitted or falsified results of blood evidence in dozens of cases. In three of those cases, the defendants were executed. Apparently from 1987-2003, prosecutors were aided by agents of the State Bureau of Investigations who were misrepresenting blood evidence and keeping crucial notes from defense attorneys as well. The above findings were a result of a review 190 cases ordered by the State Attorney General after a man was imprisoned for 17 years for a murder he didn't commit. As I have reported previously, state crime labs throughout California and the US are routinely used to prosecute people arrested for DUI / Drunk Driving.
