This clip is a brief excerpt from a Ten News at Five report from June 2013.
After 36 years, the latest search for the remains of anti-drugs campaigner and aspiring politician Donald Mackay proves fruitless and police decide to call it off.
Mackay went missing in 1977 from the central NSW town of Griffith in what appeared to be a retaliation against him by local drug syndicates. Mackay's van was found abandoned in a parking lot with bullet holes and blood stains on it, but his body was never found.
A known hitman, James Frederick Bazley, served time for conspiring to murder Mackay, while a Royal Commission named six men who possibly ordered the killing. However, no person has ever been charged with his actual murder.
