Moon Hea Koo, a 31-year-old Asian man who resold items he bought at auctions, was found dead inside a vehicle in the 6200 block of Erdman Avenue in Baltimore on April 15, 2014. Law enforcement determined his death was a homicide; an autopsy found blunt force trauma, stabbing, and asphyxiation.

The combination of injuries points to a violent struggle, but no public announcement of suspects or persons of interest has been made. There have been no arrests, and investigators have not released a motive or further details about who might be responsible.

Does anyone who knew Moon, his auction work, or his movements around that area in April 2014 have information that could help investigators?
