Unsolved: Jane Furlong. A man tells police he saw Jane Furlong a day after her disappearance, being escorted through Port Waikato’s sand dunes by a group of men carrying a spade. On the anniversary of the unsolved murder, Kelly Dennett examines his story, and considers the fallibility of memory. The scene made him so uncomfortable, he says, that he documented it. Surreptitiously turned the flash off on his black Olympus camera, told his wife to pose, and hit snap. Where that photo is now is anyone’s guess, but if it still exists – and captures what he believes he saw – it could hold the key to one of New Zealand’s most infamous cold cases.
