Police probe possible twist in serial killer case

(CNN) - Police in Gaston County, North Carolina, shot and killed a robbery suspect early Monday, and then called in police from South Carolina who have been chasing a serial killer.

There was "evidence in regard to the man that was shot," said Capt. Joe Ramey of the Gaston County Police Department.

Ramey did not give specifics, and said he could not state for certain whether the suspect had a link to the serial killer case.

"We saw evidence they needed to know about," Ramey said.

Gaston County is about 33 miles northeast of Gaffney, South Carolina. Police say a serial killer in the Gaffney area has killed five people since late June.

Police in Cherokee County, which includes Gaffney, had a basic description of the killer and the car he may be driving.

In Gaston County in the early morning hours Monday, "there was a reported burglary" at a home, said Ramey. "Officers attempted to arrest an individual with outstanding warrants." The individual resisted and shot an officer. The injured officer and another officer returned fire, killing the suspect, Ramey said.
