The accused murderer of Brisbane schoolgirl Tiahleigh Palmer will undergo a psychiatric evaluation, a court has heard.
Tiahleigh's foster father Richard Thorburn has been charged with the 12-year-old's murder.
Thorburn didn't appear at Beenleigh Magistrates Court on Wednesday as his matter was briefly mentioned.
His lawyer Adam Dwyer told the court he was seeking a psychiatric evaluation for his client before the next appearance, which was set for February 22.
Tiahleigh's mother Cindy and several supporters wearing her daughter's favourite colour purple crammed into the gallery of the small courtroom.
Upon hearing the news Thorburn would undergo psychiatric evaluation, one supporter said "he's not crazy, he's just a f***wit".
Thorburn's son Trent, who has been charged with incest and perverting the course of justice, also had his matter mentioned in the same court on Wednesday.
Trent, who is expected to make a bail application in the Supreme Court later on Wednesday, didn't appear and his matter was also adjourned until February 22.
