"I believe the hospital didn't care ... she should have been sent to a rest home."
Janet, who feels she is like a grandmother to Martin, worried she was on "borrowed time" and feared that when he was eventually released from prison there would be nobody to help him.
"He will be alone in this world. He will have no one else in this world.
"This is the true tragedy of what happened. Two people who truly loved each other, who were devoted to each other, have lost their lives."
Noeleen's brother Mate Marinovich, who lived on the same Carter Rd property as his sister and nephew, told the court the emotional harm he had suffered was indescribable.
"It has been harrowing. My life has been turned upside down from the minute the police officer knocked on my door."
He had never before experienced the kind of loneliness he now felt, he said.
"We were the best of mates," he said of his sister.
They were going to grow old together and had joked she would bring flowers to his grave.
"Now I do that for her."
Mate had felt a sense of betrayal but also suffered through "the hell" of the court process as the trial had left him with nightmares, the court heard.
He did not want his nephew condemned to a long prison sentence but rather would have been happy with the young man being electronically monitored.
Mate said the young man's father had played a "large hand" in what had happened.
