The 27-year-old was last seen in Coolamon on the afternoon of August 10, 2017. 

Samuel John Shephard, 37, is alleged to have committed the murder between 2pm and midnight on August 10 at Coolamon. 

Anthony Shane Hagan, 19, is also accused of the same murder. 

Wagga crime manager Detective Inspector Darren Cloake said it was still an open case and investigations were continuing into the location of Ms Boyd’s remains. 

"Our efforts will continue in trying to locate the body," Inspector Cloake said

"We would like to be able to return Allecha to her family and restore her dignity." 

Inspector Cloake said police were still seeking evidence and information from any members of the community who might know anything. 

A brief of evidence will be served on both Hagan’s and Shephard’s solicitors by April 24. 

Both men remain behind bars. 

Hagan, of Mount Austin, is also charged with possession of a prohibited drug, supplying a prohibited drug, possession of an unauthorised firearm, possession of ammunition without a licence and not keeping a firearm safely.  

Shephard, of Coolamon, is also charged with one count of supplying a commercial quantity of drugs, supplying drugs on an ongoing basis and knowingly dealing with proceeds of crime. The cases will return to Wagga Local Court on May 9.
