Police have charged a man and woman over the discovery of a mass greyhound dog grave in Bundaberg . A 71-year-old man and 64-year-old woman were both charged with unlawfully possessing a firearm after a police search found a rifle and ammunition in a home in Bundaberg, Queensland, on Thursday . A Queensland Police and RSPCA taskforce, set up after the greyhound racing industry was rocked by the live baiting scandal in February, also found ammunition shells from a .22 calibre gun. The pair, both from Bundaberg, will appear in the Bundaberg Magistrates Court on Friday. RSPCA spokesman Michael Beatty says it's understood the dogs were killed before a Four Corners special which exposed the horrors of the greyhound racing industry. 'The indications are that these may just be young dogs that didn't have the speed, basically. But that's really all we know,' Beatty told Fairfax media. The carcasses of more than 50 greyhounds were found at the bush site in Coonarr on Tuesday . At least 55 carcasses were found in the Coonarr area, near Bundaberg, on Tuesday, with the RSPCA. Early investigations suggest the dogs were young dogs that were killed as they were too slow . 'Unfortunately as I think most people would be aware, there's always been a lot of wastage in the greyhound industry.' Police said it was unclear how long the dogs' bodies had been there, but confirmed they were found in various states of decomposition. There were no greyhound training facilities or other connections to the racing industry in the area, a police spokesperson said. Queensland Police Minister Jo-Ann Miller expressed her outrage on Twitter after the discovery. 'Absolutely sickened that @QPSmedia and @RSPCAQLD have found the remains of 55 greyhounds. Animal cruelty in Qld won't be tolerated,' she wrote. 'The indications are that these may just be young dogs that didn't have the speed, basically. But that's really all we know,' an RSPCA spokesperson told Fairfax media . There were no greyhound training facilities or other connections to the racing industry in the area, a police spokesperson said . The taskforce was established to investigate the use of live baiting using possums, rabbits and piglets to train competitive greyhounds. It came after an ABC Four Corners expose from earlier this year sparked widespread outrage after showing racing dogs chasing and mauling live animals. So far, five people have been charged with a total of 23 offences in the state. An independent review headed up by barrister Alan MacSporran SC is also being conducted into the practice. It's expected to be completed in about three months' time. This review aims to find out how widespread the use of live baiting is in Queensland, and how it could go undetected for so long.
