Authorities announced the charges on Monday against 13 men and one woman, all of whom are reputed members of the Gangster Killer Bloods set of the Bloods street gang.
The accused ringleader, 28-year-old Bernard Green, was arrested on July 13 and charged in connection to three homicides. He also faces charges of racketeering, weapons and drug offenses and leading an organized crime organization.
It was unclear Monday whether Green had an attorney.
Among the homicides Green was charged with include the August 2005 shooting death of Sharee Voorhees, who was caught in gunfire while out on her porch.
Four others were also charged with murder.
