Brooke Grebert-Craig: Herald Sun Reporter gives an update from Erin Patterson's trial - Heather du Plessis-Allan Drive

Court's adjourned for the weekend after day four of the accused mushroom killer trial in Melbourne. 

Erin Patterson's estranged husband took the stand once again, presenting a series of texts demonstrating a strained relationship between the accused and his late parents. 

Herald Sun reporter Brooke Grebert-Craig told Heather du Plessis-Allan the messages also highlighted the pair's on and off dynamic. 

She says they had a friendship going until 2022, when it turned sour over tax returns and child support.
