CONCORD, N.C. — Two women were shot and killed Friday at a soda bottling plant 25 miles north of Charlotte, police said.

Concord police Sgt. Lisa Linker said police were looking for the shooter, who ran away from the Sun-drop Bottling Co., which manufactures soft drinks and spring water at the plant.

Linker said an employee called 911 around 10 a.m. and told dispatchers there "were two females down" at the plant. The caller reported seeing the shooter running from the scene.

Linker said police were using a helicopter and police dogs to search for the shooter.

Police said they don't know the shooter's identity or have any ideas about a possible motive. They also don't know if there was a relationship between the shooter and the victims, whose names have not yet been released.
