A sheriff's department helicopter that crashed behind a home in Albuquerque during the weekend was brought down by gunfire, authorities said Tuesday.

Investigators examining the wreckage Monday noticed what appeared to be a small hole in the windshield of the cockpit, White said. "Deputies also located several items that are consistent with a bullet that has fragmented upon impact."

Both the civilian pilot and the deputy on board when the helicopter crashed early Saturday survived with minor injuries.
