Expect the unexpected when the Magnetic Island Museum launches an exhibition . Its latest display includes "Evidence Rocks ", on which there was human tissue , seized by police during investigations into the death of a young woman, found face down in a pool of water , in the early l980s. Charged with murder , a man , with limited writing skills , was acquitted after a statement he allegedly made was ruled inadmissible because he could not have composed it on his own. The stones were kept at the old police station , later closed , the premises sold , the current owner doing a major restoration of the premises , with 52 windows , intending to possibly make it and the lock up a business venture. The latest museum display covers the background to many of the island's services, including the police.
