THE son of Graeme Kenneth Wright has told the Maryborough sitting of the Supreme Court that his father would call him twice a week asking about his ex-girlfriend Kylie Mackney and Noel Allan Clark.
Wright, on trial for Mr Clark's alleged murder, has been described as being "excessively obsessive" about Ms Mackney, with whom he had been in a relationship from 2006 to 2008.
It is alleged Wright became so jealous of Ms Mackney's new relationship with Mr Clark that he had Mr Clark lured to the Maryborough home of a co-accused on May 25, 2009, where he was allegedly beaten to death.
The court heard on Thursday that Wright's son Kenneth "Kenny" Wright continued to live at Ms Mackney's Murgon home after she and his father split.
Mr Wright, now aged 25, said on Thursday his father would call him twice a week and "ask if Noel was around" and "if they were in bed together" when Mr Clark started visiting regularly in April.
Mr Wright said his father called him on the morning of Mr Clark's death asking about Noel.
He said he continued to call twice a week until he was arrested by police in October.
Recorded interviews between Wright and detectives investigating the alleged murder were also played to the court yesterday.
In an initial interview, Wright admitted getting into a fight with Mr Clark a few weeks before his disappearance but said he had no involvement with his death.
"I might have done some silly things in my time but nothing that stupid," he said.
He told police he had heard a lot of rumours, including that Mr Clark owed a drug dealer a "heap of money" and he had "done a runner" to Tasmania.
He said he also heard that co-accused Dianna Gay Wright, known as Tory, had "cut his cock off".
Dianna Wright, no relation to the accused, did in fact cut off Mr Clark's penis before Wright and Byron Naylor allegedly dumped the body.
The body has still not been located.
Wright described Dianna Wright as a "scatterhead" who used a lot of morphine and speed.
