(MCT) — BIG BEAR LAKE, Calif.—When authorities hemmed in the man they suspected of killing three people in a campaign of revenge that has gripped Southern California, he responded as they had feared: with smoke bombs and a barrage of gunfire.

The suspect, who police believe is fugitive ex-cop Christopher Dorner, shot to death one San Bernardino County sheriff’s deputy and injured another Tuesday. He then barricaded himself in a wood cabin outside Big Bear in the snow-blanketed San Bernardino Mountains, police said.
