Overview

• Erin Patterson is on trial for allegedly poisoning three in-laws and attempting to poison a fourth with a meal containing death cap mushrooms in July 2023.
• Digital forensic expert Dr. Matthew Sorell testified that Patterson’s phone connected to cell towers near Loch and Outtrim, where death cap mushrooms were reported in 2023.
• Christine McKenzie, a former poisons specialist, confirmed she documented and removed death cap mushrooms from Loch in April 2023, later posting the findings on iNaturalist.
• The defense has challenged the precision of phone location data, arguing it cannot definitively place Patterson at the mushroom sites.
• Forensic toxicology evidence remains central, with death cap toxins discovered in meal remnants and a dehydrator linked to Patterson.
