A second person has been charged with the murder of William John Stevenson on Christmas Day.
Danielle Antionelle Kerr, 36, of Kerang, appeared in the Bendigo Magistrate's Court via video link on Monday afternoon facing one charge of murder and one charge of accessory to murder.
Ms Kerr made no bail application and was remanded to appear in the Bendigo Magistrate's Court for a committal mention on May 28.
Ms Kerr's psychiatric history was noted in the brief filing hearing.
Darren Lewis also faced the Bendigo Magistrate's Court last week, in relation to the alleged incident.
Mr Lewis, of Norman Road, Wellsford, appeared via video link last Friday morning and will also appear for a committal mention on May 28.
The court heard that extensive analysis of bone fragments was needed.
A detective will also travel to New Zealand as part of the investigation.
Homicide Squad detectives made the charges after the discovery of human remains in a burnt out vehicle belonging to missing Kerang man William Stevenson.
Mr Stevenson, 47, has not been seen since leaving a house, near where the burnt-out vehicle was found, on Christmas Day.
He was reported missing by his boss after not showing up for work at Hazeldene's Chicken two days later.
A police officer located Mr Stevenson's burnt-out car at Norman Road, in the Wellsford Forest, on January 1 during a requested search of the area.
Hazeldene's Chickens farming manager Karl Lawson told the Bendigo Advertiser on Thursday that Mr Stevenson had worked as a casual at the Prairie broiler complex since November 25 last year.
"He was a really good worker, very conscientious," Mr Lawson said.
Mr Stevenson moved to Kerang in 2012 to take a job as a driver with JRM Freight before joining Hazeldene's Chickens in November.
