James Thomas Cornell was 43 when he was shot dead in a Laurel, Maryland apartment on the night of November 21, 2012. Police responded just before midnight to the 11600 block of South Laurel Drive and found him suffering from a gunshot wound; he was pronounced dead at the scene.

Police described the apartment as the site of an illegal poker game. Investigators say at least three masked men knocked, forced the partially opened door and entered; during the intrusion Cornell was fatally shot. The Prince George’s County Police Department opened a homicide investigation, but the assailants’ identities have not been publicly revealed and no arrests have been announced.

What details about that night, the apartment’s occupants, or the people who ran the game might help solve this case?
