Suspect lied to inquest: coroner

Tasmanian man Geoffrey Charles Hunt repeatedly lied to an inquest to mask his involvement in the death of a Hobart woman more than four decades ago, a coroner says.

Simon Cooper on Monday released his findings into the August 1969 disappearance of aspiring model Lucille Gaye Butterworth, who vanished from a suburban bus stop.

He said Hunt - who lived nearby Ms Butterworth's boyfriend - offered the 20-year-old a lift and strangled her a short time later, before dumping her body near the banks of the Derwent River.

In his 68-page finding Mr Cooper rejected Hunt's denials that he knew anything of Ms Butterworth's disappearance, or that he even knew the blonde typist.

"I am satisfied that his assertion that he did not know who she was is untrue," Mr Cooper wrote.

"I am satisfied that it was a deliberate untruth."

In relation to other crucial evidence, Mr Cooper found the now-65-year-old avoided telling the truth.

Witnesses recounted seeing a car similar to Hunt's turquoise Holden stopped at the bus stop the night Ms Butterworth disappeared.

But Hunt said he only rarely used the "old bomb", which was owned by his father.

"I am satisfied that Mr Hunt's denials as to access to, and use of, a car were untrue, and deliberately so," Mr Cooper found.

Tasmania Police will review the coroner's findings and forward a report to the director of public prosecutions, who will decide if Hunt should be charged.
