Two people are dead in Cupertino, Calif., and police say the alleged shooter appears to be an employee of the Hanson Permanente quarry. Another four were seriously wounded, and a worker in the quarry says another two victims have been found; their condition is unknown. KGO-TV repots that the shootings may have occurred at the daily 4am PDT safety meeting. An employee allegedly showed up to that meeting with an automatic rifle; unconfirmed reports say the gunman remains in the quarry. (More gunman stories.)
