Susan Falls, 42, has pleaded not guilty to murdering her husband of 20 years Rodney James Falls, on May 25, 2006, at their home in Caloundra.
She’s accused of lacing her husband’s meal of curried prawns with sleeping pills and shooting him twice in the head.
Christopher Anthony Cummings-Creed, 25, Anthony James Hoare, 42 and Bradley James Coupe, 30, have also pleaded not guilty to a charge of accessary after the fact to murder.
Ms Falls confessed to killing her husband in June 2006 during a seven-and-a-half hour police interview.
The last of the tapes was played in the Supreme Court in Brisbane today.
Ms Falls said during the interview she kept her husband’s body in the house for three days before having him removed.
“It was starting to smell and I was concerned that it would be noticeable,” Ms Falls said in the taped interview.
She said she burnt incense and put on the air-conditioner to mask the smell of death.
The couple’s four children knew their father’s body was in the house, and this spurred Ms Falls to finally take action.
Mr Falls’ body was wrapped in bed linen and a blue tarpaulin and Falls allegedly sought help to dump it in the Mapleton State Forest, the court heard.
The court has previously heard Ms Falls feared for her life as her husband physically abused her over a period of years.
The trial continues.
