A Delaware grand jury has indicted 16 prison inmates for first-degree murder over a February uprising during which a guard was killed and others taken hostage, prosecutors said on Tuesday.
Floyd, 47, was found unresponsive after police stormed the prison’s C building to end the standoff. The other guards were injured, while the counselor was unharmed.
A New Castle County grand jury handed up charges against a total of 18 inmates that include assault, kidnapping, riot and conspiracy, Delaware’s Justice Department said in a statement.
A spokesman for the department said he had no information on whether the accused had legal representation.
The department’s statement did not give a motive for the uprising. Officials said at the time that the prisoners were demanding better living conditions at the center, which houses about 2,500 inmates in Smyrna, some 40 miles (64 km) south of Wilmington.
