women and vanished into the night, authorities said.
The shooting at Cascade Mall in Burlington left one man injured Friday night, said Sgt. Mark Francis, a spokesman for the state patrol.
Authorities believe only one shooter is involved and are searching for a man who headed toward Interstate 5 after the attack.
They released a blurry surveillance video picture of an armed man they described as the suspect.
His motive or relationship to the women, if any, were unclear.
Witnesses described chaotic scenes and confusion when the shooting started about 7 p.m. local time
