Fingerprints found on tape binding murdered tattooist Dwayne Robert Davies' body were of insufficient quality to find a match, a court has heard.
Mr Davies' best friend Bradley Scott Purkiss and wife Margaret Anne Otto face trial in the Hobart Supreme Court jointly accused with his murder.
Both accused have pleaded not guilty.
The Crown alleges the former lovers colluded to kill Mr Davies.

Mr Davies was last seen by Mr Purkiss on May 26, 2017, and his body was found in a shallow grave on a rural Levendale property a week later.
Earlier in the trial, the court heard evidence Mr Davies' body was found wrapped in a blue tarp bound with clear tape and blue twine.
Tasmania Police fingerprint expert Tracey Tobin told the court on Thursday five fingerprints were pulled from the tape, one from the tape bound around the knees and four from the tape around the legs.
Ms Tobin said the prints were lifted from the tape by a member of Tasmania Police using a chemical process.
"We have a specific chemical that we use that reacts with the sticky side of tape," Ms Tobin said.
Ms Tobin said all five fingerprints were of "insufficient quality" to be identified.
The court heard a total of six fingerprints matching Mr Purkiss were found on items tested for prints as part of the investigation into Mr Davies' death.
Ms Tobin said Mr Purkiss' prints were found the top of a ladder, a motorcycle, cupboard handle cover, staple gun cover and a knife box.
The Crown's final witness, who could not give evidence on Thursday due to illness, will give evidence on Friday morning.
The trial before Chief Justice Alan Blow continues.
