OAKLAND, Calif. – Gov. Arnold Schwarzenegger has ordered flags at California's state capitol flown at half-staff for the three Oakland police officers killed by a gunman.
Police said a parolee with an "extensive criminal history" opened fire at a routine traffic stop Saturday in the city and hours later gunned down members of a SWAT team who were searching for him.
Schwarzenegger headed for a meeting with Oakland police on Sunday.
A fourth police officer who was wounded Saturday is hospitalized and battling for his life.
The gunman also was killed Saturday.
The Oakland Police Department says it was the worst day in its history. Never before had three police officers been killed in the line of duty on the same day.
