TWO flatmates dumped the beloved cat belonging to the woman they are accused of murdering on a highway about two months before her death, a court has heard.
Rachel Narelle Smith, 40, and Christopher James Swan, 39, have pleaded not guilty in Brisbane Supreme Court to murdering Amanda Quirk, 32, in the Booval home the trio shared on the eve of Easter 2010.
Smith, in a police interview played on Wednesday, said she was driving with Swan, and her boyfriend, near a highway at Riverview when Swan threw the cat from the car before it came to a complete stop.
"He reckons he was taking it away for its own good," she said.
"I thought he was just going to let the cat go, let it run away.
"I didn't tell [Amanda] anything. I just said: 'I think he must have run away'.
"I wasn't going to tell her that. That would have really broke her heart."
Smith and Swan have given different versions of how Amanda died in the house they shared at 21 Dudleigh St, each minimising the role they allegedly played in her murder.
Smith said Swan tied up Ms Quirk before torturing and beating her to death.
Swan said Smith used a heavy object to kill the woman but he did not see it.
The Crown argued they are both responsible for the death but the jury must decide their criminal responsibility based on police interviews and evidence from Michelle Anne Mondientz.
Mondientz will detail an earlier assault on Amanda in bushland and her role in disposing of the body.
Smith told police she took a week to confess to police because she was scared of Swan.
"I was scared of him coming after me. I seen him murder my friend," she said.
