Joo Won Cho'si murder in Croydon continues to baffle police

April 20, 2014

The torture and murder of a kind, generous woman continues to baffle police.

The killer of well-known business owner Joo Won Choi did not leave the scene without a trace.

Around the blood spattered through her family's neat Croydon home were crucial clues: 19 fingerprints from the same unidentified person, a palm print on the front verandah, unknown DNA under Mrs Choi's fingernails and several sock imprints on the bathroom floor only visible under special lighting.

But, nearly six years on, the stabbing of the popular, generous mother remains one of Sydney's greatest murder mysteries.
