Five people died in two separate shootings in California and Missouri, police said. In the first case, police said a laid-off worker returned to his former office in Northern California on Friday and fatally shot three people.
Forty-seven-year-old Jing Wu shot two men and a woman around 4 pm at an office complex in Santa Clara, just west of San Jose. Authorities would not release the name of the business. The gunman remained at large on Friday evening as dozens of officers searched for him. He drove off in a sport-utility vehicle, Lt Mike Sellers said.
Police in O'Fallon, Missouri, said a gunman took his ex-girlfriend hostage on Friday at a health clinic in suburban St Louis and killed her before police shot him to death, the St. Louis Post-Dispatch reported.
A spokeswoman for St John's Mercy Urgent Care Center said she could not release any information.
She says everyone with the clinic "is saddened by the events this evening."
