Dave Pine, the president of the San Mateo county board of supervisors, said the suspect was employed at one of the businesses and called him a “disgruntled worker”.
The shootings are being treated as related, although the connection between the locations was not immediately clear. Police have arrested a suspect, named as 67-year-old Zhao Chunli, in connection with the shooting.
“This is a devastating tragedy for this community and the many families touched by this unspeakable act of violence,” said Corpus.
