Paul Emmanuel Sierra was 40 when he was fatally shot in Los Angeles on August 24, 2015. His death was ruled a homicide and struck family and neighbors who remembered him as a beloved member of the community.

The Los Angeles Police Department opened an investigation that included interviews and evidence gathering, but the case faced obstacles common to urban gun homicides: few immediate witnesses and limited breakthroughs reported in the months afterward. No significant arrests or public developments were reported in that period, and detectives continued to treat the investigation as active.

Anyone who knew Paul, was in the neighborhood that day, or has information that might help investigators is asked to come forward.
