Djuna Joann Benjamin, 48, of Rialto, California, was found dead in an alley in the 2000 block of Western Avenue in San Bernardino on May 4, 2012. Officers had responded to a shots-fired call in the early morning and discovered Benjamin with upper body trauma; she was pronounced dead at the scene.

At the time of the report no suspects or motives had been identified. Her killing came amid an unusually violent stretch for the city — eight homicides in nine days in late April and early May — and San Bernardino recorded 47 homicides in 2012, up from 30 in 2011. Authorities described many cases that year as gang-related while others stemmed from disputes that turned deadly. Benjamin’s case remains unsolved.

If anyone knew Djuna Benjamin, saw activity in the 2000 block of Western Avenue that morning, or has information about this homicide, please come forward.
