FREMONT, Calif. — An alleged gang member accused of firing 10 shots at two Fremont plainclothes police officers, critically wounding one of them, told investigators he didn't know the person he had shot was a law-enforcement officer, authorities said Tuesday.
Andrew Barrientos, 20, was charged Tuesday in Alameda County Superior Court with attempted murder and several other crimes in connection with the shooting Friday afternoon of Officer Todd Young in East Oakland.
