The state capital is home to the Kirkland Correctional Institution, where four inmates were fatally strangled a year ago.
The warden of a SC prison where seven inmates died during a riot needs to step down, and the FBI needs to open an investigation, the National Action Network said Tuesday. Seven inmates were killed there after fights broke out Sunday night.
Lee County Fire/Rescue and Med One assisted with a mass causality incident at Lee Correctional Institution.
The S.C. Department of Corrections said early Monday morning that an incident involving "multiple inmate on inmate altercations" in three housing units at the prison began around 7:15 p.m.
He said no officers were wounded.
Few details were offered about what had actually happened inside the facility, which is maximum security and houses around 1,600 inmates, according to Department of Corrections records.
The prison is about 50 miles east of Columbia. In 2013, Michael McCall, then the warden at Lee, said it was the most unsafe prison in SC.
Two officers were stabbed in a 2015 fight.
They say the incident resulted in 17 inmates requiring outside medical attention and seven inmates were killed.
