Justice Stephen Rothman will sentence Owen Junior Fuller for the murder of Corey Power at Young, Luke Robert Birch for the murder of Carol Penrith in Griffith and Marianne Parker for the manslaughter of her husband, Ken, at West Wyalong.

Justice Rothman will travel from Sydney to Griffith for what is believed to be the first time in the region’s history three people have been sentenced for killings at the one court sitting.

Fuller, 21 next month, bludgeoned 33-year-old father of one Corey Power to death on the street with the blunt end of a tomahawk in the early hours of August 29, 2013.

Police say the murder was the bloody end of a dispute that began with Mr Power refusing to give Fuller money he obtained from selling a generator stolen from a Young business by Fuller and another man three weeks earlier.

In sentencing Fuller for murder, Justice Rothman will take into account a number of offences committed by Fuller during a crime wave before and after the killing, including unprovoked bashings, an armed robbery, intimidation and break-ins.

Birch will be sentenced for murdering 47-year-old Ms Penrith in her home on Canal Street on November 28, 2014.

She was discovered dead after concerns for her welfare were raised by her family.

Birch, 32, was arrested the same day and later pleaded guilty to murder.

“At least he admitted it and it didn’t have to be a long trial,” Ms Penrith’s son, George Broome, told The Area News at Birch’s sentencing hearing in April.

Parker was found guilty of manslaughter, but not guilty of murder, at a trial in Griffith in April.

Parker, 58, stabbed her 55-year-old husband, Ken, to death in their Monash Street home on December 16, 2013.

A jury heard that Parker was “well intoxicated” the night she killed her husband.
