A Minneapolis judge has taken the rare step of ordering juror names to remain secret in a gang-related murder trial. It's the second time in state history a judge has decided there's a risk to jurors if their identities are known. The case involves 25 year old Keith Henderson of Minneapolis who's accused of killing a man who informed on fellow members of the Chicago-based Mickey Cobras gang. The state's first case with an anonymous jury was the Haaf murder trial in 1993. In that case, four gang members were convicted in connection with the murder of Minneapolis police officer Jerry Haaf. Arthur Martinez represented one of the defendants, Mwati "Pepi" McKenzie who was convicted of conspiracy and acquitted of murder. Martinez says there's no doubt having an anonymous jury affected his client's trial.
