Authorities say salon employee stabbed 3 co-workers

RIB MOUNTAIN, Wis. (AP) - Four people are recovering from injuries after a stabbing attack at a nail salon in the Wausau area.

Marathon County sheriff's officials say a male employee of Best Nails Salon & Spa in Rib Mountain stabbed three co-workers Monday and injured himself.

All were taken to area hospitals. Sheriff's Lt. Bill Millhausen says the man stabbed two other men and a woman. He says the woman was able to go to another nearby business where police were called.

Millhausen says two of the victims have non-life threatening injuries. He didn't know about the third victim. The suspect and three victims were the only people in the salon when the attack occurred.

The sheriff's office says the suspect's job performance was in question and may have been the motive.
