"I knew," he tells the BBC.

"I thought, 'Okay, yep, you did it, you heinous individual. You've poisoned them all'."

Dr Webster had spent the morning frantically treating two of the four people a jury this week found Erin had intentionally fed toxic mushrooms - concealed in a hearty beef Wellington lunch served at her home in July 2023.

She was convicted of the murders of her in-laws, Don and Gail Patterson, both 70, as well as Gail's sister, Heather Wilkinson, 66. Erin was also found guilty of attempting to murder local pastor Ian Wilkinson – Heather's husband – who recovered after weeks of treatment in hospital.
