Some shoppers said they ran away from the chaotic scene and did not know at the time what was going on.

Sources tell NBC Bay Area that Tejero may be the ex-girlfriend of the victim.

The woman was arrested at the scene without incident and will be booked into the county jail. Police recovered a gun and will book it as evidence, according to San Jose police Officer Albert Morales.

Police are investigating the motive and circumstances surrounding the shooting.
