Robert James Wagner pleaded not guilty to killing Gerhard Wagner in January 1999 on the opening day of his trial in the Brisbane Supreme Court on Tuesday. But crown prosecutor Philip McCarthy said evidence from witnesses would draw the jury to the “irresistible conclusion” he had murdered his uncle. Mr McCarthy claimed a shop employee would testify that Wagner made “significant purchases” less than 10 days after his uncle’s disappearance. They included a landscaping broom, goggles, protective boots, gloves and a mask. He said the employee would claim Wagner told him he was “working with acids to clean a garage wall”. The court heard Gerhard’s body and the motorbike he was riding on the day he disappeared have never been found. Gerhard Wagner was last seen by one of his closest friends. Source: News...
