Two heads have been found on a Macau beach which could be linked to other body parts found in a hotel sewerage system last week. Police sources say initial inquiries suggest the heads - both female - could be linked to the discovery of human fingers and internal organs in the drainage system of the enclave's Presidente hotel several days ago. Welding workers made the discovery of the badly decomposed heads on a beach near the site of a proposed multi-billion pataca ocean park complex close to the Hyatt hotel around 3 pm yesterday. One of the severed heads had long hair and one short. They were found wrapped in plastic bags. Police are known to be studying a videotape recording taken in the Presidente which shows a man carrying what are described as 'strange' packages. A 19-year-old mainland man who was called in for questioning in connection with the grisly finds at the hotel late last week has been ruled out as a suspect and released. At about the same time as yesterday's discovery, detectives were called to a 12th-floor flat just 150 metres from the scene of the find in Chun Hung Garden Estate to investigate mysterious bloodstains.
