THE clinically clean bedroom, missing possessions and a lack of usually busy Facebook activity had Jackie Jones "hell freaked out".
The sister of murder victim Justine Jones told Brisbane Supreme Court she had texted Richard Coburn those words after learning he was the last person seen with her on the third State of Origin night in 2010.
She said Mr Coburn tried to point the finger at another beau, Nathan Lacey, whom Justine had been dating.
"Her room smelt heavily of cleaning products, it was stripped - nothing on the mattress," she said.
"It seemed very empty ... it didn't look right."
Mr Coburn is facing trial after pleading not guilty to killing Justine and dumping her body in a wheelie bin.
Her body was found at the Nambour tip a week after she went missing.
After she went missing, her sister read two love letters showing Mr Coburn's "infatuation" with Justine.
In them, Mr Coburn told Justine "I want to spend the rest of my life with you … you are my world".
He told her he wanted them to live together and he would call her non-stop.
In another letter, he told her he missed her and thought about her "all the time".
"I love you and always will," he wrote.
"I understand you don't want a relationship but I'm prepared to wait."
Under questioning from Mr Coburn's barrister, Ms Jones conceded her sister previously had marijuana problems and that she was using ecstasy and amphetamines before her death.
When asked if Justine was addicted to alcohol, Jackie said: "Addiction is a strong word but I did think she was dependant on it".
The trial continues.
