Queensland police divers are now searching the waterways in and around a former Tauranga man's Gold Coast apartment as investigations into his suspicious death ramp up.
Sex and Chocolate band frontman Tony Williams was found dead in his Sunshine Boulevard unit on Christmas Eve.
Detectives from the Gold Coast Homicide Squad have been called in after a post-mortem examination revealed Mr Williams had suffered injuries to his head and body, believed to have been inflicted by a weapon.
On Friday, it was announced the ongoing investigation would use police divers to search waterways near Mr Williams' apartment for evidence.
Detective Acting Superintendent Brian Swan, regional crime co-ordinator, appealed for information from the public to help solve Mr Williams' murder.
"Assistance from the public often proves invaluable during these investigations," he said.
"We are asking for anyone who may have seen anything suspicious ... to call us," Mr Swan said.
Queensland police have gone online to ask for help, where grieving friends and family have also appealed for information.
On Facebook many mourners also pleaded for information.
