A missing woman alleged to have been murdered by her former partner ceased communicating with close family more than a year before her disappearance, a jury has heard.
Mark Sheridan Waden is being re-tried for the murder of former American beauty queen Priscilla Brooten, after the first trial was aborted on Tuesday due to juror misconduct.
Waden lived with Ms Brooten at the time of her disappearance in Brisbane's northern suburbs on July 5, 2018. Her body has never been found.
