A CASINO woman has escaped with a good behaviour bond for hindering a police investigation into the murder of Glen Innes greengrocer Adrian Trevett.
The NSW Supreme Court heard on Friday, Deborah Grant, 34, disposed of documents belonging to Mr Trevett who was "coldly and calculatingly" executed at a Red Range butter factory in 2010.
Mr Trevett's body was found with a rope tied around his neck, in a national park near Tenterfield in January last year.
In sentencing, Justice Geoff Below said Grant had been motivated by her loyalty to murderer Matthew Aquilina.
He said she had told Aquilina how to get rid of documents he was handed by co-accused Grafton man David Comber.
Grant was released on a 12-month good behaviour bond on the grounds she report regularly to the Casino probation and parole office and refrain from committing further offences.
Comber and his co-accused Karen Dawson were both sentenced to 23 years in jail for Mr Trevett's murder.
The court heard while Comber did not play a direct role in the cause of death - he tied the rope around the victim's neck - he was aware of another of the accused's intention to kill and remained "willing and able" to help.
He was also convicted of racking up more than $60,000 on Mr Trevett's credit card and sentenced to six months.
His then partner Kristine Weston also received a 12-month good behaviour bond.
Aquilina, who is Dawson's son, will be sentenced on March 1 next year.
