Justine Damond called police after hearing a sound in an alley near the home she shared with her fiancé late Saturday night. But shortly after two officers arrived in her upscale Minneapolis neighborhood to investigate, the call turned deadly when one of the officers shot Damond.Neither of the responding officers had turned on their body cameras, and police have not yet said why one of the officers shot her. The squad car camera did not capture the incident, either.Did the officer fire shots in response to hearing "fireworks" ?
