One of Florida's most notorious serial killers, Danny Rolling, is just hours away from his scheduled execution.
Rolling received the death penalty for the 1990 slayings of five college students in Gainesville, Florida.
Family members of at least one of his victims say they plan to be on hand for the execution.
Rolling's remaining appeal contends that the chemicals used in Florida's execution process can cause severe pain.
It is before the U.S. Supreme Court, which has turned down the same arguments in two other Florida executions this fall. His execution is slated for 6 p.m. this evening.
