AP source: Ex-cop exchanges fire with authorities

By By TAMI ABDOLLAH

LOS ANGELES (AP) — A law enforcement official says a person believed to be the fugitive ex-Los Angeles cop sought in three killings has exchanged gunfire with authorities in the San Bernardino Mountains.

The officer requested anonymity because the officer was not authorized to speak publicly about the ongoing investigation.

The officer tells The Associated Press it's believed Christopher Dorner committed a residential burglary of a cabin and had a couple tied up in the cabin. One was able to get away and make a call.

Authorities responded to the location and gave chase Tuesday when Dorner fled in a stolen car. Gunfire was exchanged.
