The gunman who killed three people and injured 13 in Gilroy, Calif., had a "target list" of religious institutions, Democratic and Republican political organizations, and federal buildings, the F.B.I. said Tuesday, announcing that it had opened a domestic terrorism investigation.
The suspect had been exploring several "competing" violent ideologies, said John F. Bennett, the F.B.I. special agent in charge in San Francisco, at a news conference.
