COLUMBIA, S.C. (AP) - An Alabama man who busted out of jail 16 years ago and fatally shot a police officer and another man in the midst of a crime spree is set to die by lethal injection Friday in South Carolina's execution chamber.

34-year-old Thomas Treshawn Ivey of Union Springs is scheduled to be executed at 6 p.m. in Columbia for killing Tommy Harrison, a 38-year-old Orangeburg police sergeant.

Authorities say Ivey's crime spree began in January 1993, when he and another inmate escaped from the Barbour County Jail in Clayton where Ivey was being held on a murder charge.

Ivey and Vincent Neuman busted out of jail, stole a truck and drove to South Carolina, ending up in Neuman's hometown of Columbia.

There, authorities say the pair kidnapped and killed a businessman.

Neuman, now 40, eventually testified against Ivey and is serving a life sentence for murder in South Carolina.
