A federal prison in Louisiana was locked down over the weekend because two inmates -- one of them from North Carolina -- apparently died because of a fight.
Authorities say William Bullock of North Carolina and Donald Till of Florida died in hospitals Thursday from wounds suffered in an assault.
Officials did not say when the incident occurred, nor did they or describe the injuries. A prison spokesman says the cause of death is being investigated.
This is at least the third lock-down since April because of violence at the high-security prison in Pollock, Louisiana. The prison was locked down in July after two inmates were stabbed in the stomach during a fight in the prison yard, and for a month in April, after two inmates died from puncture wounds in the neck from a homemade weapon.
That fight that killed two inmates.
